Chapter 14, Problem 88E

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the unpolluted ${\text{CO}}_2$ saturated rain and the concentration of ${\text{H}}_3{\text{O}}^{+}$ in the ${\text{CO}}_2$ saturated rain are to be calculated.

Concept Introduction:

The $\text{pH}$ is defined as the negative logarithm of the concentration of ${\text{H}}_3{\text{O}}^{+}$. Mathematically it is expressed as;

$\text{pH}=-\text{log}\left[{\text{H}}_3{\text{O}}^{+}\right]$

The $\text{pH}$ of the acidic solution is less than 7.
