Chapter 14, Problem 41E

Interpretation Introduction

Interpretation:

The concentration and volume of acetic acid and the required $\text{pH}$ of solution is given. The mass of sodium acetate that must be added to make a buffer solution with acetic acid is to be calculated.

Concept introduction:

The $\text{pH}$ value is the measure of ${\text{H}}^{+}$ ions. The relation between $\text{pH}$ and $\text{p}{K}_{\text{a}}$ is given by the Henderson-Hassel Bach equation. According to this equation,

$\text{pH}=\text{p}{K}_{\text{a}}+\log \frac{\left[\text{Base}\right]}{\left[\text{Acid}\right]}$
