CBSE Class 11 Chemistry Practical Syllabus with Marking Scheme

In chemistry subject practical also plays a vital role. Students understand the theory by performing the experiments in the lab. So, its important that students must also know CBSE Syllabus of Chemistry Practical and list of experiments included in it. Also, the weightage of Chemistry practical is of 30 marks. So, students must try to score well in practicals also. It will help in increasing their overall score. The table below shows the evaluation scheme of practical exams.

  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:
  2. 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.
  3. Comparing the pH of solutions of strong and weak acids of same concentration.
  4. Study the pH change in the titration of a strong base using universal indicator.
  5. Study the pH change by common-ion in case of weak acids and weak bases.

D. Chemical Equilibrium

  1. One of the following experiments:
  2. Study the shift in equilibrium between ferric ions and thiocyanate ions by increasing/decreasing the concentration of either of the ions.
  3. Study the shift in equilibrium between [Co(H2O)6]2+and chloride ions by changing the concentration of either of the ions.
