Chapter 15, Problem 67AE

Interpretation Introduction

Interpretation:

Whether a solution of strong acid with 3 as $\text{pH}$ can have changed $\text{pH}$ ion upon dilution with water and whether $\text{pH}$ of 7 or beyond could be achieved has to be identified.

Concept Introduction:

The acidity strength is quantified by the magnitude of a parameter called $\text{pH}$. The strong acids tend to 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 concentration of ${\text{H}}^{+}$ ions.
