Chapter 15, Problem 15.90QE

Interpretation Introduction

Interpretation:

The ICE table and equation required needed to calculate the ${\text{H}}_3{\text{O}}^{+}$ in $1.5M{\text{ NH}}_{\text{4}}\text{Cl}$ has to be written.

Concept Introduction:

The ionization of a hypothetical weak acid $\left(\text{HA}\right)$ is given as follows:

  $\text{HA}\left(\text{aq}\right)+{\text{H}}_{\text{2}}\text{O}\left(\text{l}\right)\rightleftharpoons {\text{A}}^{-}\left(\text{aq}\right)+{\text{H}}_3{\text{O}}^{+}\left(\text{aq}\right)$

The relation among $K_{\text{a}}$, $K_{\text{b}}$ and $K_{\text{w}}$ is given as follows:

  $K_{\text{a}}{K}_{\text{b}}=K_{\text{w}}$

Here,

$K_{\text{w}}$ denotes the ionic product of water.

$K_{\text{a}}$ denotes the ionization constant of weak acid.

$K_{\text{b}}$ denotes ionization constant of weak base.
