(a)

Interpretation Introduction

Interpretation:

The compound ${\left({\text{CH}}_{\text{3}}\right)}_3\text{N}$ is strong or weak acid, strong or weak base is to be classified.

Concept introduction:

The acids which have higher value of acid dissociation constant $\left(K_a\right)$ is the strong acid and they are completely dissociated into the aqueous solution but the acids which have a lower value of acid dissociation constant $\left(K_{\text{a}}\right)$ is called weak acid and they are not completely dissociated into the aqueous solution.

The bases which have higher value of base dissociation constant $\left(K_{\text{b}}\right)$ is the strong bases and they are completely dissociated into the aqueous solution but the bases which have a lower value of bases dissociation constant $\left(K_{\text{b}}\right)$ is called weak bases and they are not completely dissociated into the aqueous solution.

The strong acid has a stable conjugate base, as the stability of the conjugate base is increased, the acidity of the acid will be increased.

The basicity is increased if the availability of the electron pair on the base is increased.

(b)

Interpretation Introduction

Interpretation:

The compound $\left(\text{HI}\right)$ is strong or weak acid, strong or weak base is to be classified.

Concept introduction:

The acids which have higher value of acid dissociation constant $\left(K_a\right)$ is the strong acid and they are completely dissociated into the aqueous solution but the acids which have a lower value of acid dissociation constant $\left(K_{\text{a}}\right)$ is called weak acid and they are not completely dissociated into the aqueous solution.

The bases which have higher value of base dissociation constant $\left(K_{\text{b}}\right)$ is the strong bases and they are completely dissociated into the aqueous solution but the bases which have a lower value of bases dissociation constant $\left(K_{\text{b}}\right)$ is called weak bases and they are not completely dissociated into the aqueous solution.

The strong acid has a stable conjugate base, as the stability of the conjugate base is increased, the acidity of the acid will be increased.

The basicity is increased if the availability of the electron pair on the base is increased.

(c)

Interpretation Introduction

Interpretation:

The compound $\left(\text{HBrO}\right)$ is strong or weak acid, strong or weak base is to be classified. And also $\left(K_a\right)$ an expression for a weak acid is to be written.

Concept introduction:

The acids which have higher value of acid dissociation constant $\left(K_a\right)$ is the strong acid and they are completely dissociated into the aqueous solution but the acids which have a lower value of acid dissociation constant $\left(K_{\text{a}}\right)$ is called weak acid and they are not completely dissociated into the aqueous solution.

The bases which have higher value of base dissociation constant $\left(K_{\text{b}}\right)$ is the strong bases and they are completely dissociated into the aqueous solution but the bases which have a lower value of bases dissociation constant $\left(K_{\text{b}}\right)$ is called weak bases and they are not completely dissociated into the aqueous solution.

The strong acid has a stable conjugate base, as the stability of the conjugate base is increased, the acidity of the acid will be increased.

The basicity is increased if the availability of the electron pair on the base is increased.

(d)

Interpretation Introduction

Interpretation:

The compound $\text{Ca}{\left(\text{OH}\right)}_2$ is strong or weak acid, strong or weak base is to be classified.

Concept introduction:

The acids which have higher value of acid dissociation constant $\left(K_a\right)$ is the strong acid and they are completely dissociated into the aqueous solution but the acids which have a lower value of acid dissociation constant $\left(K_{\text{a}}\right)$ is called weak acid and they are not completely dissociated into the aqueous solution.

The bases which have higher value of base dissociation constant $\left(K_{\text{b}}\right)$ is the strong bases and they are completely dissociated into the aqueous solution but the bases which have a lower value of bases dissociation constant $\left(K_{\text{b}}\right)$ is called weak bases and they are not completely dissociated into the aqueous solution.

The strong acid has a stable conjugate base, as the stability of the conjugate base is increased, the acidity of the acid will be increased.

The basicity is increased if the availability of the electron pair on the base is increased.
