Chapter 20, Problem 20.50QP

Interpretation Introduction

Interpretation:

From the given equilibrium constant, the $\text{pH}$ of rain water has to be calculated.

Concept Introduction:

• $\text{pH}$ is the logarithm of the reciprocal of the concentration of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ in a solution.
•  $\text{pH}$ is used to determine the acidity of an aqueous solute.
• $\text{pH}\text{=}{\text{-log[H}}_{\text{3}}{\text{O}}^{\text{+}}\text{]}$
