CBSE Syllabus for Class 11 Chemistry Practical 2020-21

PRACTICAL SYLLABUS                                                                                                     Total Periods: 44

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
2. Bending a glass tube
3. Drawing out a glass jet
4. Boring a cork

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. Quantitative Estimation
i. Using a mechanical balance/electronic balance.
ii. Preparation of standard solution of Oxalic acid.
iii. Determination of strength of a given solution of Sodium hydroxide by titrating it against standard solution of Oxalic acid.
iv. Preparation of standard solution of Sodium carbonate.
v. Determination of strength of a given solution of hydrochloric acid by titrating it against standard Sodium Carbonatesolution.

D. Qualitative Analysis
a) Determination of one anion and one cation in a given salt
Cations‐ Pb2+, Cu2+, As3+, Al3+, Fe3+, Mn2+, Ni2+, Zn2+, Co2+, Ca2+, Sr2+, Ba2+, Mg2+, NH4 +
Anions – (CO3)2‐ , S2‐, NO2 , SO32‐, SO2‐ , NO , Cl , Br, I‐, PO43‐ , C2O2‐ ,CH3COO
(Note: Insoluble salts excluded)

b) 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 sulphideion
• 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 (ifany).
• 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 tealeaves.
• Determination of the rate of evaporation of different liquids
• Study the effect of acids and bases on the tensile strength offibers.
• 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.
