Chapter 13, Problem 95E

Interpretation Introduction

Interpretation: The major species present in $0.150\text{M}$ ${\text{NH}}_{\text{3}}$ solution are to be stated. The $\left[{\text{OH}}^{-}\right]$ and the $\text{pH}$ value of the given solution is to be calculated.

Concept introduction: The $\text{pH}$ of a solution is define as a figure that expresses the acidity of the alkalinity of a given solution.

The $\text{pH}$ of a solution is calculated by the formula, $\text{pH}=-\log \left[{\text{H}}^{+}\right]$

The $\text{pOH}$ of a solution is calculated by the formula, $\text{pOH}=-\log \left[{\text{OH}}^{-}\right]$

The sum, $\text{pH}+\text{pOH}=14$
