Chapter 7, Problem 122E

Interpretation Introduction

Interpretation: The pH of $5.0\times {10}^{-8}\text{ M}$ HNO₃ solution needs to be calculated.

Concept Introduction: A strong acid completely dissociate into hydrogen ion and its conjugate base.

The pH of the solution can be calculated as follows:

  $\text{pH}=-\log \left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$

Here, $\left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$ is hydronium ion concentration.
