Chapter 13, Problem 100E

Interpretation Introduction

Interpretation: The $\text{pH}$ of the given ${\left({\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\right)}_2\text{NH}$ solution is to be calculated.

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

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

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

At equilibrium, the equilibrium constant expression is expressed by the formula,

$K_{\text{b}}=\frac{\text{Concentration}\text{of}\text{products}}{\text{Concentration}\text{of}\text{reactants}}$
