1. Determination of the melting point of an organic compound.

2. Determination of the boiling point of an organic compound.

3. Crystallisation of an impure sample of any one of the following: Alum, Copper Sulphate, Benzoic Acid.

3. Experiments based on pH

1. Any one of the following experiments:

• Determination of pH of some solutions obtained from fruit juices, solutions of known and varied concentrations of acids, bases and salts using pH paper or universal indicator.

• Comparing the pH of solutions of strong and weak acids of the same concentration.

• Study the pH change in the titration of a strong base using a universal indicator.

2. Study the pH change by common-ion in case of weak acids and weak bases.

4. Chemical Equilibrium

Any one of the following experiments:

• Study the shift in equilibrium between ferric ions and thiocyanate ions by increasing/decreasing the concentration of either of the ions.

• Study the shift in equilibrium between [Co(H2O)6] 2+ and chloride ions by changing the concentration of either of the ions.

5. Quantitative Estimation

CBSE Class 11 Chemistry Projects 2026

Scientific investigations involve laboratory testing and collecting information from other sources.

A few suggested Projects

a) Checking the bacterial contamination in drinking water by testing the sulphide ion

b) Study of the methods of purification of water

c) Testing the hardness, presence of Iron, Fluoride, Chloride, etc., depending upon the regional variation in drinking water and study of causes of presence of these ions above the permissible limit (if any).

d) Investigation of the foaming capacity of different washing soaps and the effect of the addition of Sodium carbonate on it

e) Study the acidity of different samples of tea leaves.

f) Determination of the rate of evaporation of different liquids

g) Study the effect of acids and bases on the tensile strength of fibres.

h) Study of the acidity of fruit and vegetable juices.

Note: Any other investigatory project, involving approximately 10 periods of work, can be chosen with the teacher's approval.
