Chapter 14, Problem 53E

(a)

Interpretation Introduction

Interpretation:

The concentration and volume of ${\text{HC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ is given. The quantity (moles) of $\text{NaOH}$ that must be added to produce buffer solution is to be calculated from the given conditions.

Concept introduction:

A solution that contains mixture of a weak acid and its conjugate base is known as buffer solution. The $\text{pH}$ value is the measure of ${\text{H}}^{+}$ ions.
