Chapter 15, Problem 15.78QE

(a)

Interpretation Introduction

The chemical equation corresponding to ionization of chlorite ion formate ion has to be written and base ionization constant has to be calculated.

Concept Introduction:

The ionization of a hypothetical weak base is given as follows:

  $\text{B}\left(\text{aq}\right)+{\text{H}}_{\text{2}}\text{O}\left(\text{l}\right)\rightleftharpoons {\text{BH}}^{\text{+}}\left(\text{aq}\right)+{\text{OH}}^{-}\left(\text{aq}\right)$

The relation among, ${\text{K}}_{\text{b}}$ 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.

(b)

Interpretation Introduction

The chemical equation corresponding to ionization of fluoride ion has to be written and base ionization constant has to be calculated.
