Chapter 14.4, Problem 32PP

Interpretation Introduction

Interpretation:

“Aniline, $C_{6}H-N{H}_2$ a weak base $K_b$ of $4.0\times {10}^{-10}$ , reacts with water to form with $C_{6}H-N{H}_3^{+}$ and hydroxide ion. Write the equation for the reaction and the base dissociation constant expression for aniline.” should be explained

Concept introduction:

The $\text{pH}$ of any solution is defined as the negative logarithm of the hydrogen ion concentration.

  $\begin{array}{l}pH=-\log \left[H^{+}\right]\\ \text{or}\\ \left[H^{+}\right]={10}^{-pH}\end{array}$
