Chapter 10, Problem 10.13P

Interpretation Introduction

Interpretation:

Molarity of $\text{NaOH}$ has to be calculated.

Concept Introduction:

Formula to compute $\text{pH}$ for a buffer is as follows:

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

Here,

$\text{p}{K}_{\text{a}}$ is characteristic of a weak acid.

$\left[\text{Salt}\right]$ denotes the concentration of salt formed.

$\left[\text{Acid}\right]$ is concentration of acid left undissociated.
