Deleted syllabus of class 11 physics

The following portion to be deleted

  1. Experiments based onpH
    a) 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.
  1. b) Study the pH change by common-ion in case of weak acids and weak bases.
    Chemical Equilibrium

One of the following experiments:

  1. a) Study the shift in equilibrium between ferric ions and thiocyanate ions by increasing/decreasing the concentration of either of theions.
  2. b) Study the shift in equilibrium between [Co(H2O)6]2+ and chloride ions by changing the concentration of either of theions.
