Chapter 15, Problem 22RQ

Interpretation Introduction

Interpretation:

The two whole numbers before and after $\text{pH}$ lies for a solution that has $\text{0}\text{.003 M}$ concentration of ${\text{H}}^{+}$ ion has to be determined.

Concept Introduction:

The acidity strength is quantified by the magnitude of a parameter called $\text{pH}$. The strong acids tend to have lower values of $\text{pH}$. This is since $\text{pH}$ represents the negative logarithm of the concentration of ${\text{H}}^{+}$ ion. So higher the concentration of ${\text{H}}^{+}$ ion lower will be $\text{pH}$.

The expression to evaluate $\text{pH}$ is as follows:

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

Here,

$\left[{\text{H}}^{+}\right]$ denotes the concentration of ${\text{H}}^{+}$ ions.
