Chapter 16.4, Problem 6PE

Interpretation Introduction

Interpretation: The information regarding the confusion in the consideration of concentration of ${\text{H}}_3{\text{O}}^{+}$ ions produced by auto ionization of water in the rainwater sample is given. The $\text{pH}$ of rainwater sample for the given concentration of ${\text{H}}_3{\text{O}}^{+}$ and ${\text{H}}_2{\text{CO}}_3$ is to be calculated.

Concept introduction: The $\text{pH}$ of an acid determines the concentration of Hydrogen or Hydronium ions that are present in the solution.

To determine: The $\text{pH}$ of rainwater sample.
