Chapter 7, Problem 105E

(a)

Interpretation Introduction

Interpretation: The concentration of hydrogen ion, hydroxide ion and pH of the solution needs to be determined.

Concept Introduction: The pH of the solution will be:

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

The relation between hydrogen ion and hydroxide ion concentration is as follows:

  $\left[{\text{H}}^{+}\right]=\frac{K_w}{\left[{\text{OH}}^{-}\right]}=\frac{{10}^{-14}}{\left[{\text{OH}}^{-}\right]}$
