Chapter 14, Problem 14.95SP

(a)

Interpretation Introduction

Interpretation:

Using ${\text{K}}_{\text{a}}$ value of ${\text{F}}^{\text{-}}$, ${\text{K}}_{\text{b}}$ value for ${\text{F}}^{\text{-}}$ has to be calculated.

Concept Introduction:

Acid dissociation constant $\left({\text{K}}_{\text{a}}\right)$:

It is an equilibrium constant which refers the dissociation (ionization) of an acid. The value of ${\text{K}}_{\text{b}}$ can be calculated by using ${\text{K}}_{\text{a}}$ and vice versa.  This relation is given as,

${\text{K}}_{\text{b}}\text{=}\frac{{\text{K}}_{\text{w}}}{{\text{K}}_{\text{a}}}{\text{ or K}}_{\text{a}}\text{=}\frac{{\text{K}}_{\text{w}}}{{\text{K}}_{\text{b}}}$

(b)

Interpretation Introduction

Interpretation:

Using ${\text{K}}_{\text{a}}$ value of ${\text{OBr}}^{\text{-}}$, ${\text{K}}_{\text{b}}$ value for ${\text{OBr}}^{\text{-}}$ has to be calculated.

Concept Introduction:

Acid dissociation constant $\left({\text{K}}_{\text{a}}\right)$:

It is an equilibrium constant which refers the dissociation (ionization) of an acid. The value of ${\text{K}}_{\text{b}}$ can be calculated by using ${\text{K}}_{\text{a}}$ and vice versa.  This relation is given as,

${\text{K}}_{\text{b}}\text{=}\frac{{\text{K}}_{\text{w}}}{{\text{K}}_{\text{a}}}{\text{ or K}}_{\text{a}}\text{=}\frac{{\text{K}}_{\text{w}}}{{\text{K}}_{\text{b}}}$

(c)

Interpretation Introduction

Interpretation:

Using ${\text{K}}_{\text{a}}$ value of ${\text{HS}}^{\text{-}}$, ${\text{K}}_{\text{b}}$ value for ${\text{HS}}^{\text{-}}$ has to be calculated.

Concept Introduction:

Acid dissociation constant $\left({\text{K}}_{\text{a}}\right)$:

It is an equilibrium constant which refers the dissociation (ionization) of an acid. The value of ${\text{K}}_{\text{b}}$ can be calculated by using ${\text{K}}_{\text{a}}$ and vice versa.  This relation is given as,

${\text{K}}_{\text{b}}\text{=}\frac{{\text{K}}_{\text{w}}}{{\text{K}}_{\text{a}}}{\text{ or K}}_{\text{a}}\text{=}\frac{{\text{K}}_{\text{w}}}{{\text{K}}_{\text{b}}}$

(d)

Interpretation Introduction

Interpretation:

Using ${\text{K}}_{\text{a}}$ value of ${\text{S}}^{\text{2-}}$, ${\text{K}}_{\text{b}}$ value for ${\text{S}}^{\text{2-}}$ has to be calculated.

Concept Introduction:

Acid dissociation constant $\left({\text{K}}_{\text{a}}\right)$:
