Answer to Problem 55A

The given reaction is a type of acid base reaction which is shown below:

  HNO3 + KOH  H2O + KNO3

Explanation of Solution

The given reaction is a type of acid base reaction which is shown below:

  HNO3 + KOH  H2O + KNO3

When a strong acid (HNO3) reacts with strong base (KOH) it will produce salt (KNO3) and water (H2O) in acid base reaction.

(b)
