Explanation / Answer

16. Solution of equal amount of -

Strong acid + Weak base = Acidic

Strong acid + Strong base = Neutral

Weak acid + Strong base = Basic

Weak acid + Weak base = Neutral

In the question we are given ammonia a weak base and perchloric acid a strong acid , so its solution will be acidic.

Option (a) is correct.

17. At equivalence point there are equal number of H+ and OH- . They will neutralise each other and the solution will be neutral.

H+   + OH-   -----> H2O

For a neutral solution pH is 7.

Option (c) is correct.
