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.

The school physics lab has several pieces of equipment that need to be maintained. Let us segregate the equipment into categories and tackle them one by one. 

Electrical Equipment Management for your School Physics Lab

Electrical equipment in school physics laboratories is susceptible to rust due to humidity, penetration of dust and short circuits. While dust and humidity can affect its efficacy, short circuits can lead to flames, fires or electric shocks. Always monitor and replace faulty equipment listed below: 

Prone to Rust and Dust:

• Ammeters/Voltmeters

• Galvanometers
• Wheatstone Bridges

• Resistance Box

Prone to short circuits and accidental discharge, acid leakage and electric shocks:

• Lead Accumulators

• Alkaline Accumulators
• Battery Chargers

While rust damaged ammeters cause faulty readings, short circuits or acid leaks can cause severe harm to students working in the lab. 

Protocol for Maintenance of Measurement Instruments

Measurement instruments are used to record values during experiments. If they are faulty, it can lead to incorrect readings. This can cause significant distress to students especially during board exam practical, where final results obtained are crucial. Test this equipment from time to time and replace/repair if necessary:

• Vernier Calipers
• Screw Gauge
• Lenses & Prisms
• Barometers

All instruments are important for sensitive measurements, where the least count is very low. So, the equipment needs to be sensitive and properly maintained and calibrated. 

Optical Bench Cleaning and Storage

Store all equipment in closed spaces to avoid unnecessary exposure to dust and humidity. Now, when storing equipment that is long, spacious cabinets are needed. It is difficult to store optical benches for this reason, and it is kept outside for prolonged periods of time. This causes dirt to accumulate on the lenses and tracks. 

Labkafe offers ergonomic lab furniture which helps you store optical benches without the hassle. They are equipped with foldable door cabinets, which can be used to store optical benches or other long equipment.  

General Equipment Storage and Maintenance

• Standard Labeling – Each piece of equipment must be stored in separate spaces that are clearly marked and labeled eg: optics, electricity, magnetism, etc. This prevents the loss of small items like loose wires, screws, or pins. Students should be taught to store all equipment properly after completing experiments.
• Silica Gel Use – To control humidity, especially in tropical countries like India, use silica gel-based adsorbents. These helps absorb moisture in storage spaces, preventing mold and fungi growth. Silica gel is particularly useful for storing lenses and optical devices.
• Weight-Based Organization – Stack and store equipment based on weight. Lighter items should be placed on top, while heavier items should be stored at the bottom to maintain stability and prevent damage.

2. How to Maintain School Physics Lab Furniture?

Physics lab equipment must have ergonomic furniture that is designed to accommodate large equipment, like meter bridges and optical benches. Additional furniture needed might be:

• Stools– for seating students when teaching experiments
• Boards– to write and instruct students on how to perform the experiment

Dealing with Mischief

Maintain strict discipline in the lab by enforcing rules. Do not allow any unprofessional conduct, such as fooling around with apparatus, throwing lab objects here and there and chatting or unrelated conversations that can distract focus from the experiments being performed. 

4. Cleaning & Maintenance Schedule for the School Physics Lab

Follow these steps to maintain the lab properly:

Daily Maintenance

Wipe down equipment exteriors with a 70:30 mixture of ether and alcohol for regular cleaning. 

Weekly Maintenance

Once in a while, you should strip down equipment, preferably during weekends when students do not need the physics lab equipment. Deep clean equipment properly with proper procedure, as instructed by the supplier for respective equipment. You can’t clean a meter bridge and a concave lens the same way! Consult manuals or the lab manager for specific cleaning processes. 

Specialized Equipment Maintenance

For high end equipment, follow this protocol:

• Six-monthly checks by an engineer
• Weekly surface cleaning
• Monthly QC control checks

Your lab equipment supplier should provide a maintenance and cleaning schedule along with the correct procedure tailored to your school physics lab. If not, it might be time for a change!

Biological Safety Cabinet Diagram showing the air inlets and outlets, position of the HEPA filters, air circulation pathway and the workspace. 

Definition

The biological safety cabinet filters incoming and outgoing air from the cabinet, which is ventilated. The ventilated cabinet is where the worker places the substance they are working with and continues to process it, preferably wearing additional protective equipment, such as masks, gloves, safety goggles and PPE kits.

1. HEPA Filters: The filters are fitted with HEPA (High-Efficiency Particulate Air) filters, which remove incoming air contaminants.
2. Filtration Efficiency: HEPA filters can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and airborne particles ≥ 0.3 microns (µm) (USEPA).
3. Alternative Names: Also known as a laminar flow cabinet or tissue culture hood.
4. Safe Handling Practices: All procedures should be performed in a way that minimizes aerosol generation and prevents spills.
5. Aerosol-Generating Procedures: 

These include:

• Centrifugation
• Vortex
• Sonication
• Opening containers of infectious materials (with internal pressure different from ambient pressure).

6. Containment Measures: Such procedures should be performed inside the biological safety cabinet or additional safety measures should be implemented to mitigate risks.

Classes of Biological Safety Cabinets

Biological Safety Cabinet Class 1

The Class I biological safety cabinet has a simple and fundamental design. It provides protection for the operator and the environment by drawing inward airflow that captures aerosols generated during microbiological work. This air then passes through a filtration system, typically consisting of a pre-filter and a HEPA filter, which removes airborne particles and contaminants before being exhausted.

• User & Environment Protection: Class I cabinets protect the operator but not the sample.
• Cross-Contamination Risk: Exposure to airborne contaminants may affect experimental accuracy.
• Limited Applications: Restricted use due to contamination risks.
• Obsolescence: Largely replaced by Class II cabinets for better protection.

Biological Safety Cabinets Class 2

The Class II Biosafety Cabinet is primarily used for handling pathogenic biological samples or applications requiring a sterile work environment. It is designed with three key protective features:

1. Inflow air – Protects the operator by preventing exposure to hazardous materials.
2. ULPA/HEPA-filtered downflow – Maintains an ISO Class 3 clean work surface, preventing cross-contamination and ensuring sample integrity.
3. ULPA/HEPA-filtered exhaust – Safeguards the environment by filtering outgoing air before release.

These features make Class II cabinets essential in microbiology, pharmaceuticals, and biomedical research. This is the most commonly used biosafety cabinet in schools, colleges and research institutions. To set up a biosafety level 2 cabinet in your organization, go over here. 

Biological Safety Cabinets Class 3

Class III biological safety cabinets offer the highest level of containment, surpassing Class I and II cabinets. However, they are much costlier. 

• Construction: Made of welded metal, gas-tight, with glove ports for handling materials.
• Negative pressure: Maintains negative pressure to enhance containment safety.
• HEPA filtration: Exhaust air is HEPA-filtered and incinerated for additional safety.
• Material transfer: Uses a pass-through unit for safe transfer of materials.
• Air exhaust: Air is typically exhausted back into the lab or through a dedicated duct system to the external environment.
• Toxic chemical compatibility: Suitable for use with toxic chemicals in addition to microbiological work when connected to dedicated exhaust systems.

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

Wash Bottle – For rinsing the conical flask

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. Aesthesiometric Index (Two Points)

The Aesthesiometric Index is a test that is used to test the minimal distance between two points on the skin that can be stimulated separately. Imagine if two points on the skin are touched separately, they would be registered by your brain as two different points of contact. This is true as long as the two points are far apart. But as we bring the points closer, we would reach a stage where the two points would become indistinguishable. This minimum distance of separation is called the Aesthesiometric Index. The Aesthesiometric Index test allows us to measure this distance.

2. Pass Along Test

The pass along test is used to measure the intelligence of people between the ages of 7 to 20 years. The subject moves blocks along a tray to match a predetermined design. 

The Pass Along test

3. Block Design Test

The Block Design Test measures a subject’s visuospatial and visuoconstructive abilities. These abilities help us read time on a clock, set up clocks with accurate time, read maps and find correct directions while navigating. The performance of individuals in this test declines with age, with younger individuals performing better than older individuals.

4. Cube Construction

This is a test of spatial ability, where subjects need to perform cube rotation tasks mentally. It is a subjective test where the test individual creates his or her own answer to the computerized test. It is a spatial ability test that measures abstract intelligence through the folding and unfolding, construction and deconstruction of cubes in blank 3D space. 

5. Locus of control test (1 unit)

People who believe that they can control their lives by themselves and that their own actions primarily determine what happens to them in the future, are said to believe in intrinsic factors of control and they are said to have an internal locus of control. When people believe that external factors or instances, such as luck, control their lives and the consequences thereon, the person is said to have an external locus of control. They believe that external factors have a greater influence on their life, than internal factors. The test consists of a set of questions that the subject needs to answer. This leads to the calculation of a score, that tells the evaluator, whether the subject holds an internal or external locus of control. 

6. Self confidence Inventory (Hindi) by K.N. Sharma (1 unit)

Helps identify self-esteem areas, especially in young adults, that need improvement. It is also a questionnaire that needs to be answered by the subject, consisting of 25 statements that the individual can compare themselves to. It has a gradient from 1 to 4 on the answer scale and the subject may return later to retake the test. This will show them if they have made improvements.

7. Bell Adjustment Inventory (Hindi adaptation) (1 unit)

This test consists of 124 items. The inventory measures 4 different dimensions of adjustment such as Home, Health, Social and Emotional and another dimension separately, named Overall. Home adjustment is expressed in terms of satisfaction or dissatisfaction with home life. Health Adjustment, in the terms of shyness, submission, introversion, Emotional adjustment in terms of depression, nervousness etc. High Score in the inventory indicates low adjustment and vice versa.

8. Thematic Apperception Test (Mehrotra) (1 unit)

The Thematic Apperception Test, also known as TAT, is a projective test that focuses on the subconscious dynamics of a person’s personality. The test uses ambiguous pictures and was created in the 1930s by Henry A. Murray and Christina D. Morgan to understand a person’s subconscious motives in relation to achievements, power, and intimacy.

9. Rorschach Test (1 unit)

The Rorschach test, also known as the inkblot test, is a psychological test that involves showing people a series of inkblots and asking them to describe what they see. The test is used to assess personality traits, emotional functioning, and thought disorders.

10. Word Association Test (1 unit)

The word association test uses a person’s ability to associate words with tangible phenomena. When a word is assigned to the person, they are requested to write down the first thoughts that come to them. This allows evaluators to understand the psychology and cognitive function of the person.
