Chapter 7, Problem 108E

(a)

Interpretation Introduction

Interpretation:

The pH of $0.10{\text{ M CH}}_3{\text{NH}}_3\text{Cl}$ should be calculated.

Concept Introduction :

The pH of a solution can be calculated from hydrogen ion concentration as follows:

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

Here, $\left[{\text{H}}^{+}\right]$ is hydrogen ion concentration.

(b)

Interpretation Introduction

Interpretation:

The pH of $0.050\text{ M NaCN}$ should be calculated.

Concept Introduction :

The pH of a solution can be calculated from hydrogen ion concentration as follows:

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

Here, $\left[{\text{H}}^{+}\right]$ is hydrogen ion concentration.
