Chapter 10, Problem 10.11P

Interpretation Introduction

Interpretation:

$\text{pH}$ at equivalence point for titration between $0.100\text{ M}$ of hydroxyacetic acid and $0.050\text{ M}$ of $\text{KOH}$ has to be calculated.

Concept Introduction:

Formula to compute $\text{pH}$ for a salt formed from a weak acid and strong base is as follows:

  $\text{pH}=\frac{1}{2}\left(\text{p}{K}_{\text{w}}+\text{p}{K}_{\text{a}}+\log \left[\text{Salt}\right]\right)$

Here,

$\text{p}{K}_{\text{w}}$ is characteristic of ionic product of water.

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

$\left[\text{Salt}\right]$ denotes the concentration of salt formed from weak acid and strong base.
