Chapter 14, Problem 111CP

Interpretation Introduction

Interpretation: The formation of a buffer solution by the addition of $\text{NaOH}$ to a solution of $\text{HOCl}$ is given. The volume of $\text{NaOH}$ that must be added to the solution to achieve a $\text{pH}$ equal to $8$ is to be calculated.

Concept introduction: The solution of weak acid and their conjugate base which upon addition of an acid or base resists the change in $\text{pH}$ is called buffer solution. The $\text{pH}$ of the buffer solution remains constant.
