Question

How hydrogen and hydroxyl ion concentration gets affected in acidic and basic solutions respectively when (i) an acidic solution is further diluted (ii) more amount of base is added to a basic solution?​

Answer 1

Answer:

Add few drops of solution from all three test tubes on the red litmus paper separately. The solution which turns red litmus to blue contains basic solution. Use this blue litmus paper to test the solutions in other two test tubes. The solution from the test tube which turns blue litmus paper to red will be the acidic solution and solution of the test tube which do not change either red or blue litmus paper contain water.
