CBSE Chemistry Practical Deleted Syllabus for Class 11

Experiments based on pH

Any one of the following:

  • 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 the same concentration.
  • Study the pH change in the titration of a strong base using a universal indicator.
