Chapter 14, Problem 119E

Interpretation Introduction

Interpretation: The $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ of acid rain is to be calculated for the given value of pH. The calculated $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ of acid rain is to be compared with that of $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ of west coast rain.

Concept Introduction: The pH of the solution is:

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

The $\text{pH}$ scale is basically used to classify the solution as:

If the solution has pH less than 7, then it is acidic.

If the solution has pH greater than 7, then it is basic.

If the solution has pH equals to 7, then it is neutral.
