Chapter 7, Problem 160CP

Interpretation Introduction

Interpretation: The volume of water that must be added to make the pH value 5.00 needs to be determined.

Concept Introduction: From the given pH value, hydrogen ion concentration can be calculated as follows:

  $\left[{\text{H}}^{+}\right]={10}^{-pH}$

From hydrogen ion concentration, hydroxide ion concentration can be calculated as follows:

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