Chapter 17, Problem 98GQ

Interpretation Introduction

Interpretation:

For the given buffer which contains $0.10{\text{ M CH}}_3\text{COOH}$ and $0.10{\text{ M CH}}_3\text{COONa}$ the value of buffer capacity has to be determined.

Concept introduction:

A buffer is defined as a solution which does not show any change in its $\text{pH}$ values on addition of small amount of acid or base.There are two types of buffer solutions, (1) Acidic Buffer  (2) Basic Buffer.

Buffer capacity is defined as on addition of acid and base in $1\text{ L}$ solution of buffer change in its $\text{pH}$ value is unity. This is called as buffer capacity. It is denoted by $\beta$. When the ratio of acid and its base or vice-versa is unity then change in $\text{pH}$ value is zero.
