Chapter 16, Problem 16.5QE

(a)

Interpretation Introduction

Interpretation:

Whether the given $0.100M$ ammonia and $0.100M$ ammonium nitrate solution is buffer solution or not has to be identified.

Concept introduction:

Buffer:

A buffer is a solution that can resist pH change upon the addition of an acidic or basic component. Buffer solution used to maintain the pH of the solution, when the small amount of acid or bases is added.

Buffer solution is containing of weak acid and its conjugate base, or weak base and its conjugate acid. Buffer solution is very important for the specific pH reaction where the stable pH is needed.

(b)

Interpretation Introduction

Interpretation:

Whether the given $0.100M$ ammonia and $0.100M$ acetic acid solution is buffer solution or not has to be identified.
