Chapter 7, Problem 136AE

Interpretation Introduction

Interpretation: The number of moles of HCl added to 1.0 L of 2.0 M NaOH needs to be calculated to make pH equals to 0.00.

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:

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