Check and download the CBSE Class 11 Chemistry Practical Syllabus 2022-2023 in PDF here. Check experiments and projects prescribed for the CBSE Class 11 Chemistry Practicals.   

CBSE Class 11 students in the Science stream must understand the value of practicals that help them in improving their basics and clear the concepts. Practicals carry a weighatge of 30 marks towards the annual assessment. Students should learn to perform all the experiments mentioned in the latest CBSE Syllabus. We have provided below the CBSE Class 11 Chemistry Practicals Syllabus that has been released for the current academic session, 2022-2023. Check below the list of experiments, evaluation scheme and projects suggested for the annual assessment. Students can check and download the CBSE Class 11 Chemistry Syllabus 2022-2023 in PDF.

PRACTICAL SYLLABUS (Total Periods: 60) 

Micro-chemical methods are available for several of the practical experiments, wherever possible such techniques should be used.

A.Basic Laboratory Techniques 

1. Cutting glass tube and glass rod

3. Drawing out a glass jet

B.Characterization and Purification of Chemical Substances 

1. Determination of melting point of an organic compound.

2. Determination of boiling point of an organic compound.

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

C.Experiments based on pH

1. 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 indicator.

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

D.Chemical Equilibrium One of the following experiments:

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

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

1. Using a mechanical balance/electronic balance.

2. Preparation of standard solution of Oxalic acid.

3. Determination of strength of a given solution of Sodium hydroxide by titrating it against standard solution of Oxalic acid.

4. Preparation of standard solution of Sodium carbonate.

5. Determination of strength of a given solution of hydrochloric acid by titrating it against standard Sodium Carbonate solution.

1.Determination of one anion and one cation in a given salt

Cation: Pb2+, Cu2+ As3+, Aℓ3+, Fe3+, Mn2+, Zn2+, Ni2+, Ca2+, Sr2+, Ba2+, Mg2+, NH4+

Anions: (CO3) 2- , S2- , (SO3) 2- , (NO2) - , (SO4) 2- , Cℓ- , Br- , I- , (PO4) 3- , (C2O4) 2- , CH3COO-, NO3 -

2.Detection of -Nitrogen, Sulphur, Chlorine in organic compounds.

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.

• Study the effect of acids and bases on the tensile strength of fibers.

• 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.
