Chapter 22, Problem 33E

Interpretation Introduction

Interpretation:

The $\text{pH}$ of a typical antiseptic solution that is $\text{3}.0\%{\text{ H}}_{\text{2}}{\text{O}}_{\text{2}}$ by mass needs to be determined.

Concept introduction:

The $\text{pH}$ is the measure of hydrogen ion concentration in the solution.

Formula of $\text{pH}$ is as follows:

$\text{pH=}-\log \left[{\text{H}}^{+}\right]$

Here, $\left[{\text{H}}^{+}\right]$ is hydrogen ion concentration.
