Chapter 15, Problem 44PE

(a)

Interpretation Introduction

Interpretation:

Out of the four classes amongst strong and weak acid, strong base, or weak base, class of ${\left(\text{COOH}\right)}_2$ has to be identified and equation when ${\left(\text{COOH}\right)}_2$ is dissolved in water has to be identified.

Concept Introduction:

An electrolyte refers to an ionic compound that on solvation in polar protic solvents ionizes to yield cationic and anionic species. The free movement of such ionic species results in the conduction of electricity.

Three subcategories exist for electrolyte namely strong electrolyte, weak electrolyte and non-electrolyte. The strong electrolytes on dissolution exhibit $100\text{ \%}$ dissociation; in contrast, the weak electrolytes are not $100\text{ \%}$ dissociated. However, the non-electrolytes barely dissociate or do not dissociate at all.

(b)

Interpretation Introduction

Interpretation:

Out of the four classes amongst strong acid, weak acid, strong base, or weak base, class of $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}$ has to be identified and equation when $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}$ is dissolved in water has to be identified.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Out of the four classes amongst strong acid, weak acid, strong base, or weak base, class of ${\text{HClO}}_4$ has to be identified and equation when ${\text{HClO}}_4$ is dissolved in water should be identified.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

Out of the four classes amongst strong acid, weak acid, strong base, or weak base, class of $\text{HBr}$ has to be identified and equation when $\text{HBr}$ is dissolved in water has to be identified.
