- Bending a glass tube
- Drawing out a glass jet
- Boring a cork
B. Characterization and Purification of Chemical Substances
- Determination of melting point of an organic compound.
- Determination of boiling point of an organic compound.
- Crystallization of impure samples of any one of the following: Alum, Copper Sulphate, Benzoic Acid.
C. Experiments based on pH
- Any one of the following experiments:
- Determination of pH of some solutions obtained from fruit juices, solution of known and varied concentrations of acids, bases and salts using pH paper or universal indicators.
- Comparing the pH of solutions of strong and weak acids of same concentration.
- Study the pH change in the titration of a strong base using a universal indicator.
- Study the pH change by common-ion in case of weak acids and weak bases.
D. Chemical Equilibrium
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.
E. Quantitative Estimation

Scientific investigations involving laboratory testing and collecting information from other sources.
A few suggested Projects
- Checking the bacterial contamination in drinking water by testing sulphide ion
- Study of the methods of purification of water
- 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 permissible limit (if any).
- Investigation of the foaming capacity of different washing soaps and the effect of addition of Sodium carbonate on it
- Study the acidity of different samples of tea leaves.
- Determination of the rate of evaporation of different liquids
- <red> ❌<red> Study the effect of acids and bases on the tensile strength of fibres.
- Study of acidity of fruit and vegetable juices.
NOTE: Any other investigatory project, which involves about 10 periods of work, can be chosen with the approval of the teacher.
