School Administrators, Teachers and Authorities face a hard time trying to maintain the school chemistry lab. Here is the ultimate guide to running your school chemistry lab smoothly. Keep reading for cleaning, repair and safety guidelines.

How to Maintain the School Chemistry Lab Equipment?

Each piece of equipment in the chemistry lab needs to be maintained properly:

Glassware

1. Beaker – A simple container for mixing, stirring, and heating chemicals. Store glass beakers after rinsing with soap and water in the lower rack of a cabinet with glass doors. This prevents dust from falling into the beaker that can disrupt experiments. 
2. Conical Flask (Erlenmeyer Flask) – Used for mixing and heating solutions with reduced risk of spills. Store and clean flasks like beakers. 
3. Test Tubes – Small glass tubes used for holding, mixing, and heating substances. Store them in boxes with holders. Always keep the boxes in a well-ventilated closed place after cleaning, like a glass door almirah or cupboard. 

4. Test Tube Holder – A clamp used to hold test tubes during heating. Keep ample holders in the lab, so that all students have enough holders to use during experiments. If enough holders aren’t there, students resort to hacks like using paper holders as a makeshift or using the test tube as is during heating. This is very risky, because the paper can catch fire, or the reagents in the tube can boil out, harming the student. Hence, test tube holders are a must for every school chemistry lab. 
5. Measuring Cylinder (Graduated Cylinder) – Used to measure liquid volumes accurately. Store them along with glassware, ensure dust and humidity does not affect the equipment. 
6. Watch Glass – A concave glass used for evaporating small amounts of liquid or covering beakers. Store like other glassware. 

Additional Equipment

1. Bunsen Burner – A gas burner used for heating substances. Teach students to stop the gas supply after use. Ensure it is closed after experiments and beware of gas leaks. 
2. Wire Gauze – A mesh placed over a tripod stand to distribute heat evenly.
3. Crucible and Lid – A heat-resistant container for high-temperature heating. Prone to breakage upon falling, must be handled carefully. 
4. Evaporating Dish – Used to evaporate liquids and concentrate solutions.
5. Pipette – A tool for transferring precise amounts of liquid. Each student should be assigned a separate pipette for titration experiments. Mouth pipettes are unhygienic to share. 
6. Burette – A long graduated tube used in titration to measure liquid volume precisely. Teach students to handle the burette carefully. The long burette is often broken by students during handling. Fill the burette by keeping the burette and stand setup on the ground. Then place it on the benchtop to perform titration drop by drop. 
7. Dropper – A small tool for adding liquid dropwise. 
8. Glass Stirring Rod – Used for stirring solutions manually. Replace broken or cracked glass rods as they can cause injury. 
9. Funnel – Used for transferring liquids and filtering mixtures.
10. Filter Paper – A porous paper used to separate solids from liquids. Keep them inside packed boxes, to protect from dust and humidity. 
11. pH Paper – A strip of paper that changes color to indicate acidity or alkalinity. They must be kept absolutely dry.

You might be wondering how to deal with humidity in tropical countries. The best way is to store the apparatus or equipment for the school chemistry lab in a closed cupboard and then put silica gel in corners in the cupboard. It will absorb the moisture, keeping the apparatus dry, hence rust and bacteria free.

These worktops are easy to clean and maintain, making them a preferred choice for fixed lab casework.

Phenolic Resin Worktops

Phenolic resin worktops are lightweight yet durable, weighing 7.2 pounds per square foot at one-inch thickness. They are made by layering recycled paper with phenolic resin and applying extreme heat to form a solid surface. These worktops resist bacteria, chemicals, moisture, and moderate to high corrosion. They can withstand continuous heat exposure up to 350°F. The surface comes in different colors, but the core is usually black. They are commonly used in biological, chemical, clinical, and analytical labs.

Stainless Steel Worktops

Stainless steel worktops offer the best hygienic and antimicrobial properties. They are made of chromium and nickel, making them highly resistant to rust, corrosion, and high temperatures (over 1500°F). These non-porous surfaces are commonly used in biomedical, pharmaceutical, food testing labs, and hospitals. They are long-lasting, easy to clean, and resistant to heat and chemicals, making them suitable for sterile environments.

Chemical Resistant Laminate Worktops

Chemical-resistant laminate worktops are made by coating phenolic resin onto kraft paper and covering it with a synthetic resin. These worktops resist chemicals and can handle heat exposure up to 275°F. They are used in labs that require non-contaminated surfaces, such as dental, pathology, urology, photographic darkrooms, and product testing labs. Their decorative surface makes them aesthetically appealing while maintaining high resistance to laboratory chemicals.

Wood Worktops

Wood worktops, typically made of rock maple, provide a sturdy and long-lasting surface. End-grain wood is used for strength by gluing smaller blocks together. These worktops have poor moisture and bacterial resistance but offer a warm and rich appearance. They are primarily used in mechanical labs where aesthetics and durability are essential.

Trespa Worktops

Trespa worktops are highly versatile and suitable for various laboratory applications. Made using reinforced natural fibers and thermosetting resins bonded under high pressure, they are impact-resistant, moisture-resistant, and chemical-resistant. They are also scratch-resistant, easy to clean, and durable. Trespa worktops are commonly used in pharmaceutical laboratories.

PVC Laminate Worktops

PVC laminate worktops are made by compressing polyvinyl chloride layers under extreme pressure. They offer excellent chemical resistance, moisture resistance, and durability, making them ideal for high-traffic laboratory environments. These worktops are also cost-effective and low maintenance, requiring only mild cleaning agents. They provide various design options, from monochromatic to multicolored finishes, making them suitable for different lab settings. PVC laminate is heat-resistant and impact-resistant, ensuring longevity in demanding lab conditions.

Theory

Potassium permanganate is a strong oxidant in the presence of sulfuric acid. Mohr salt is a double salt forming a single crystalline structure having the formula FeSO₄.(NH₄)₂SO₄.6H₂O. The chemical name for Mohr’s salt is ferrous ammonium sulfate.

In this titration Mohr salt acts as a reducing agent and potassium permanganate acts as an oxidizing agent. Acid Base Titration with Mohr’s Salt against KMnO4 is an example of redox reaction. In this redox reaction, ferrous ion from Mohr’s salt gets oxidized and pink colored of manganese present in potassium permanganate, which is in the +7-oxidation state gets reduced to colorless Mn²⁺ state.

The chemical reaction and the molecular chemical equation is given below.

Reduction half reaction –

2KMnO₄ + 3H₂SO₄ → K₂SO₄ + 2MnSO₄ + 3H₂O + 5[O]

Oxidation half reaction –

[2FeSO₄(NH₄)₂SO₄.6H₂O + H₂SO₄ + [O] → Fe₂(SO₄)₃ + 2(NH₄)₂SO₄ + 13H₂O] x 5

Overall reaction –

2KMnO₄ + 10FeSO₄(NH₄)₂SO₄.6H₂O+ 8H₂SO₄ → K₂SO₄+ 2MnSO₄+ 5Fe₂(SO₄)₃+ 10(NH₄)₂SO₄+ 68H₂O

Apparatus

We will need the following to perform Acid Base Titration with Mohr’s Salt Against KMnO4 as an example:

Burette – Filled with KMnO₄ (Potassium Permanganate) solution

Conical Flask – Contains 10 mL of Ferrous Ammonium Sulfate (Mohr’s salt) and sulfuric acid

Pipette – To accurately measure and transfer Mohr’s salt solution

Funnel – To fill the burette without spillage

Retort Stand with Clamp – To hold the burette securely

White Tile (optional) – To enhance visibility of the color change at the endpoint

Distilled Water – For dilutions and rinsing apparatus

Procedure for Acid Base Titration example with Mohr’s Salt and KMnO₄

Setup for Acid Base Titration example with Mohr’s Salt Against KMnO₄ (Image- Byju’s)

Acid Base Titration with example Mohr’s Salt Against KMnO4 is performed as follows:

• Wash the burette with distilled water, then KMnO₄.
• Fill the burette with KMnO₄ using a funnel up to the zero mark at the top. Do this while the burette is on the ground, as filling it while placed on a table can be difficult—lab benches are high, and many students take practical exams in schools other than their own. This might mean performing the experiment on unfamiliar lab benches. 
• Always remember to remove air from the nozzle by opening the stopcock slightly. This ensures accuracy. Dispense the excess KMnO₄ into a separate test tube to prevent spills on the table. The nozzle tip holds some volume. The total volume is measured from the tip to the zero mark at the top of the burette.
• Fill the burette with excess KMnO₄ initially and drain it until the level reaches the zero mark. Note the upper meniscus for these experiments.

• Use a glass pipette to transfer Mohr’s salt. Partially block the pipette’s opening with your finger and gently inhale to draw the solution into the pipette. This helps pull in enough solution. The ring marked at the top of the stem indicates the 20 mL marking for this 20 mL glass pipette.
• After filling the pipette, keep your finger in place and release it when ready to dispense the Mohr’s salt solution into the conical flask. Ensure the flask is washed with soap and clean water and dried completely to prevent interference with reaction volumes.

• Each drop must be dispensed into the flask, as even a single drop remaining in the pipette could affect your final reading. If you want to avoid using a mouth pipette, you can also use a 20 mL test tube to transfer the Mohr’s salt solution.
• Open the burette stopcock slowly and dispense the KMnO₄ drop by drop. Maintain your eye level parallel to the markings on the burette to avoid parallax error. Keep rotating the conical flask in a circular motion to ensure proper mixing.

• Approximately 17–20 mL of KMnO₄ is usually required. Carefully monitor the measurement once the burette crosses the 17 mL mark. At this point, control the stopcock with one hand while continuing to rotate the conical flask with the other.
• Take three readings to find the final average value, as this provides a more accurate result. This is also required as per Board Exam rules. 
• The endpoint is when a light pink color first appears, not when the solution becomes dark pink or violet. Stop the burette stopcock immediately as soon as the solution turns light pink.

• The moment the solution turns light pink, take the reading from the burette. This reading indicates the amount of KMnO₄ required to neutralize the Mohr’s salt solution.

Calculations for this Acid Base Titration Example

Normality of KMnO₄ solution:

Consider y ml of given KMnO4 solution is equivalent to 20 ml of N/10 Mohr’s salt solution.

According to law of equivalents,

N1V1 = N2V2

N1, N2 are normality of Mohr’s salt and KMnO4 solution respectively.

V1, V2 are volumes of Mohr’s salt and KMnO4 respectively.

1/10 x 20 = N2 x y

N2 = 2/y

N = Normality of given KMnO4 solution = 2/y

Strength of KMnO₄ solution:

Strength = Normality x Equivalent mass

Equivalent mass of KMnO4 =

= 158/5

= 31.6

= 2/y x 31.6 g/liter

Molarity of KMnO₄ solution:

N = M x Number of electron gained

N = M x 5

M = N/5 moles/ liter

The strength of and molarity of a given KMnO4 solution is found out as 2/y x 31.6 g/l and N/5 moles/liter, respectively.

Results and Discussion

Molarity of given KMnO4 solution is _________ moles/liter

The strength of given potassium permanganate solution is _______ g/L

Acid Base Titration Example- Precautions

Beware of these traps if you don’t want to feel like this student during your practical exam.

Acid Base Titration with example Mohr’s Salt Against KMnO₄ must be done with these secret tips in mind. This will give you an edge over other candidates.

• Don’t dispense a large amount of KMnO₄ at once initially, as this can lead to errors. Even if you have an estimated value in mind, other issues may arise, and the reaction will take longer to complete.
• Keep rotating the conical flask continuously—do not stop even for a second. If you stop by mistake, the KMnO₄ will not mix properly and will remain in the solution. Later, when it dissolves, the color will appear much darker than needed, meaning the endpoint has been crossed. To prevent this, ensure you keep stirring and stop precisely at the point where the solution turns light pink. A single extra drop can result in a deeper pink color, making your reading inaccurate.

Beware of Mechanical Errors during Acid Base Titration

• Never attempt to add excess KMnO₄ to the burette if you miss the correct endpoint. If you exceed the endpoint and try to adjust by adding more KMnO₄ to the burette to match the expected reading (you know what I mean), it will be a serious mistake. Not only is this considered cheating, which may lead to penalization, but it could also irritate the examiner.
• When you present your result to the examiner, they will check both the burette reading and the color of the solution in the conical flask. If the solution appears darker than the expected light pink, they will know the reading has been manipulated. The correct amount of KMnO₄ cannot produce a darker solution if the concentrations of KMnO₄ and Mohr’s salt are accurate.
• If you make a mistake, repeat the entire experiment. Generally, board practical exams provide ample time to perform three repetitions, with extra time available if needed. Use this opportunity to carefully repeat the experiment and ensure that this time, you stop precisely when the solution reaches the endpoint and turns light pink.

The Acid Base Titration with example Mohr’s Salt against KMnO4 is a common experiment often asked in CBSE, ICSE and State board practical exams.

Frequently asked VIVA Questions for this Acid Base Titration Example

1. What is titration?

Titration is a laboratory technique used to determine the concentration of an unknown solution by reacting it with a solution of known concentration. It involves the gradual addition of a known solution to an unknown solution until the reaction reaches its endpoint.

2. What is the endpoint in titration?

The endpoint is the point at which the reaction is complete. It is usually indicated by a color change in the solution when using an indicator or when a stable reading is observed in instrumental titrations.

3. Why should titrations be performed drop by drop near the endpoint?

Adding too much titrant at once can overshoot the endpoint, leading to inaccurate results. Dispensing drop by drop ensures precise observation of the color change and prevents errors.

4. Why do we remove air bubbles from the burette before titration?

Air bubbles in the burette nozzle can cause inaccurate readings, as they can lead to an incorrect volume of titrant being dispensed. Removing air ensures precise measurements.

5. What is a standard solution in titration?

A standard solution is a solution with a precisely known concentration. It is used as the titrant to determine the unknown concentration of another solution.

6. Why is sulfuric acid added in the titration of Mohr’s salt with KMnO₄?

Sulfuric acid provides an acidic medium, which is necessary for the redox reaction between KMnO₄ and Mohr’s salt to occur correctly. Without it, the reaction might not proceed efficiently.

1.Clear your basics when preparing for a practical examination

Practical examinations might seem like a separate segment altogether, but they are deeply interconnected with the theoretical lessons taught in class. Theory helps students grasp the fundamental concepts, understand key principles, and then apply them practically. If students fail to understand the basics, it becomes very difficult to perform well in the practical exam. Therefore, focus on mastering the fundamentals during theoretical lessons. 

Don’t try to memorize concepts; instead, understand how things work and practice exercises thoroughly. This will help you handle practical exams with ease. Always remember that theory comes before practice—both are equally important, but one isn’t useful without the other. Use online resources when textbooks fall short, for bite-sized content that aids visualization.

2. Understanding experimental concepts during preparation

The next step after mastering basic theory is relating it to practical classes. Practical classes are held in separate modules for a reason: to ensure that students learn how to bridge the gap between theory and experiments. First, read everything in the lab manual carefully. If you have doubts, wait for the lessons to begin. A school or college practical lesson will not only demonstrate the experiment but also explain the material in the lab manual. 

By the end of the lesson, both the manual and the teacher’s explanations should be crystal clear. If you have any doubts, don’t hesitate to raise them during class. This will ensure your understanding of the experimental concepts is complete.

3. Perform the experiments yourself when preparing for a practical examination

When you are given the opportunity, make the most of it. Study the apparatus carefully, relate it to the manual as much as possible, and then to your instructor’s lessons. Follow the steps precisely and wait for accurate results. Always remember to follow all the precautions mentioned in the manual and by your teacher. If the experiment is performed correctly, you should obtain the expected result. 

Don’t worry if you don’t get it at first; ask your instructor. Mistakes can happen initially, and that’s how you learn. In fact, making mistakes early on teaches you what to be cautious about during the exam, so you don’t waste valuable time. If you perform experiments diligently and as instructed, you will develop the skill and confidence to perform them effectively in the exam laboratory.

4. The benefit of additional knowledge when preparing for a practical examination

Beyond the literature in your lab manual, your teacher will provide additional insights, and you might have doubts as well. Make sure to ask your teacher and note everything down in your notebook—you never know what information might be useful later. Your teacher’s insights may prove essential, especially during a Viva Voce. Ensure that you understand everything about the theoretical basics of the experiment. 

Look up extra information using reliable sources on the internet, like this YouTube channel from Labkafe. Follow bite-sized content, such as YouTube shorts, to quickly grasp concepts. Clear any knowledge gaps and research potential Viva questions. Record their answers in a notebook and revise them regularly to stay prepared for the exam. Additional information beyond the textbook is particularly useful for oral exams.

Nerves of steel will seal the deal

If you have followed the blueprint above, your chances of success will increase manifold. Remember to keep calm, rest assured that you have prepared your best and carry the essential items with you: your revision notebook and any lab safety gear you might need, like aprons. To purchase them, visit here.

During the exam, mishaps do occur, so follow precautions and be careful. Don’t lose your patience if your experimental results do not yield expected outcomes. Remember the range of values you obtained in each experiment during classes; this will help you understand the correctness of your results during the exam. 

If your experiment does not work in the exam, be sure to ask the examiner for assistance. Don’t worry if they seem strict; they will help you in times of distress. Be obedient and follow their instructions. Exams seldom require you to memorize the entire protocol, so even if you forget something, focus on the basics, and you will find a resolution.

Stay focused, prepare well, and ace your exams! All the best!

Basic Elements of the Modern Periodic Table Chart

The Modern Periodic Table has 18 vertical columns, called groups, and 7 horizontal rows, called periods. Each element in a group has the same number of valence (outer shell) electrons, resulting in similar chemical properties across the group. 

As we move down a group, the number of electron shells increases, while the number of valence electrons remains constant. In contrast, moving from left to right across a period increases the number of valence electrons by one, as the atomic number also increases by one unit.

In the third period of the Modern Periodic Table, for example, elements like Na, Mg, Al, Si, P, S, Cl, and Ar are organized based on the filling of electrons in the K, L, and M shells. The maximum number of electrons each shell can hold is calculated by the formula 2n², where “n” is the shell number from the nucleus.

For instance, the K shell holds 2 electrons (since 2 × 1² = 2), giving the first period 2 elements, while the L shell holds 8 electrons (2 × 2² = 8), giving the second period 8 elements. Although the M shell can hold up to 18 electrons (2 × 3² = 18), only 8 are filled in the third period due to the limitation on the outermost shell.

Trends Observed in the Modern Periodic Table Chart- Periodic Table Properties

Valency:

The valency of an element is based on the number of valence electrons in its outermost shell. Across a period, valency increases as the number of valence electrons increases from left to right and then decreases. In a group, valency remains the same because the number of valence electrons does not change.

Atomic Size:

Atomic size, defined as the distance between the nucleus and the outermost shell, varies across the table. Moving left to right along a period, the atomic radius decreases due to an increase in nuclear charge, which pulls electrons closer to the nucleus, reducing atomic size. Down a group, however, atomic size increases because additional electron shells increase the distance between the nucleus and the outermost electrons, despite the increased nuclear charge.

Metallic and Non-metallic Character:

Metals like Na and Mg are on the left side of the table, while non-metals like sulfur and chlorine are on the right. Metalloids, such as silicon, fall in the middle, exhibiting properties of both metals and non-metals. A zig-zag line on the table separates metals from non-metals. Elements like boron, silicon, germanium, arsenic, antimony, tellurium, and polonium lie along this line and are classified as metalloids due to their intermediate properties.

Reactivity:

As effective nuclear charge on valence electrons increases across a period, elements are less likely to lose electrons, reducing metallic character. Conversely, down a group, the distance of the outer electrons from the nucleus increases. This makes it easier to lose electrons thus enhancing metallic character. Non-metals, being electronegative, tend to gain electrons to form bonds. This trend places non-metals towards the top right of the Periodic Table.

Oxide Nature:

Predicting the nature of oxides is also possible from periodic trends. Generally, metallic oxides are basic, whereas non-metallic oxides are acidic, aligning with the positions of metals and non-metals on the table.

The power of hydrogen, or pH (also called the potential of hydrogen), measures the concentration of hydrogen ions in a solution. The formula for calculating the pH of a liquid is:

pH = -log [H⁺]

A higher pH indicates lower acidity and higher alkalinity in the solution. Conversely, a lower pH means higher acidity and lower alkalinity.

What is the effect of Power of Hydrogen pH on humans?

The concentration of hydrogen ions in a solution greatly affects humans. This concentration determines whether a substance is acidic or basic. But why should we care about the acidity of things? Highly acidic substances can harm our skin and internal organs if we come into contact with them. For example, battery acid is highly acidic and can cause severe damage upon contact.

Now, think about it: why does acidic stuff burn your skin?

Acids cause burns primarily due to their protons, or free H⁺ ions, which are loosely bound to an electronegative atom within the acid. Most acids consist of an electronegative atom bonded to a hydrogen ion or proton. These electronegative atoms tend to release the proton readily if it finds a lone electron pair to stabilize its positive charge. 

In this process, the electronegative atom bonds with a more positively charged entity that stabilizes it more effectively. Consequently, the acid donates the lone hydrogen ion to the nearest lone electron pair. This aligns with the Lowry-Bronsted definition of acids, which states that acids donate protons.

For this reaction to occur, a lone electron pair must be available. Acids donate H⁺ ions to obtain electrons, but how does this relate to the sensation of burning? Specifically, why do strong acids cause more severe burns?

Strong acids release their protons more easily, which increases their capacity to cause burns. Our bodies are made up of proteins, which fold into precise structures to function correctly. When these structures are disrupted, proteins lose their ability to function. When a strong acid comes in contact with skin, it donates protons to the proteins in the skin.

Protein unfolding

Proteins accept these protons due to the presence of carboxylate groups, which carry a negative charge. This negative charge participates in hydrogen bonds and salt bridges, which contribute to the stability of the protein’s structure. When the carboxylate group accepts a proton from the acid, it loses its negative charge, which disrupts the salt bridges and hydrogen bonds. As a result, the protein loses its secondary and tertiary structures and collapses, becoming unfolded.

The lone pair of electrons from the carboxylate group of the protein scavenges protons from the acid, causing the collapse of the protein’s secondary structure. This collapse disrupts the protein’s function, as the secondary structure is essential for its proper activity.

When this structural collapse occurs, the cells fill with nonfunctional proteins. We experience this process as a burn—acid protons alter enough proteins in the cells, causing them to clump into nonfunctional masses. This is the damage we see when tissue is burned by a strong acid.

How to measure acidity and basicity?

The mathematical value of power of hydrogen (pH) is determined by the formula:

pH = -log [H⁺]

But how do we measure hydrogen ion concentration in a solution? One way to do this is by using a pH meter, also known as a potentiometric pH meter. We will explore why it has this name shortly.

To measure pH, immerse the pH meter into the solution. The meter measures the pH directly and displays the result on a digital screen, showing the solution’s pH value. 

A higher pH or power of hydrogen indicates lower acidity and higher alkalinity in the solution. 

Conversely, a lower pH means higher acidity and lower alkalinity.

What is a pH meter?

A pH meter consists of two electrodes: a glass electrode and a reference electrode. Both electrodes have a silver wire coated with silver chloride. The silver metal in the electrode can lose electrons and become a positively charged silver ion (Ag⁺). This reaction is reversible, meaning the silver ion can also gain electrons and form metallic silver.

Another important reaction is the interaction between silver ions and chloride ions to form silver chloride (AgCl). The reference electrode is filled with saturated KCl, while the glass electrode contains 0.1M HCl.

The glass electrode has a thin glass bulb made of silica (SiO₂). The oxygen atoms bound to the silicon atoms on both the inner and outer surfaces of the glass are negatively charged. These negatively charged oxygen atoms attract positively charged hydrogen ions (H⁺). When bound by H⁺ ions, a hydrated gel layer forms on both sides of the glass bulb. The hydrogen ions cannot pass through the glass layer; they can only bind to the surface of the glass bulb.

The hydrated gel layer is about 10 nm thick, while the glass layer itself is approximately 0.1 mm thick. The glass electrode half-cell is connected to the reference electrode. The reference electrode has a porous ceramic plug, which allows the diffusion of ions and helps complete the circuit.

How does a pH meter work?

Power of Hydrogen in Acidic solutions

When the solution is acidic and you immerse the pH meter in it, more H⁺ ions bind to the outer layer of the glass bulb. This causes the region outside the glass electrode to become more positively charged, while the inner layer, with fewer H⁺ ions, remains less positively charged.

The inner solution of the glass electrode contains HCl, which releases H⁺ ions. These ions help balance the charge across the glass bulb by neutralizing the charge from the binding of hydrogen ions in the outside solution. This process causes the concentration of H⁺ ions inside the glass electrode to decrease slightly. 

However, the total number of H⁺ ions inside the glass electrode remains constant. As the H⁺ concentration is constant, the pH also remains constant. But since the free H⁺ concentration decreases, the concentration of free Cl⁻ ions increases.

At the silver wire, silver atoms lose electrons and bind with chloride ions to form silver chloride (AgCl). The electrons freed from the silver atoms are present in the silver wire of the electrode. These electrons create an electric current, which generates a voltage in the silver wire. The device measures the change in potential of the glass electrode and silver wire against the reference electrode, which serves as a standard for the glass electrode’s potential. Visit this site for a video explanation. 

Power of Hydrogen in Alkaline solutions

In an alkaline solution, the concentration of H⁺ ions in the outer layer of the glass electrode is lower than the concentration inside the glass electrode. The outer region becomes less positively charged, while the inner layer, with more H⁺ ions, becomes more positively charged. To balance the net charge, H⁺ ions from the inner layer are released into the solution inside the glass electrode. This increases the concentration of free H⁺ ions in the glass electrode. To neutralize this excess of H⁺ ions, AgCl from the silver wire dissociates into silver and chloride ions. The chloride ions balance the extra hydrogen ions in the solution.

Now, excess Ag⁺ ions are present in the solution. These ions accept electrons from the electrode and gain electrons to become metallic silver, which then deposits onto the electrode. Since the glass electrode now gives electrons, it becomes positively charged, and the potential changes. This change in potential is measured in reference to the reference electrode.

In both acidic and alkaline solutions, the potential difference is a measure of the power of hydrogen or pH value. The device translates this value into a pH reading, which appears on the digital screen. The pH meter provides an accurate reading when properly calibrated. Visit this site for a video explanation. 

Water has a pH of roughly 7

Where to buy a pH meter?

We at Labkafe provide the best quality lab equipment, including pH meters calibrated for daily laboratory use.
