Chapter 14, Problem 65E

Interpretation Introduction

(a)

Interpretation:

Whether ${\text{ZnCO}}_3\left(s\right)$, a strong or weak electrolyte is to be stated.

Concept introduction:

The strong electrolytes are those electrolytes having aqueous solution as good conductor of electricity. The solutions that ionize completely are known as strong electrolytes. The solution which does not ionizes completely and has aqueous solution as poor conductor is known as weak electrolyte.

Interpretation Introduction

(b)

Interpretation:

Whether $\text{Sr}{\left({\text{NO}}_3\right)}_2\left(aq\right)$, a strong or weak electrolyte is to be stated.

Concept introduction:

The strong electrolytes are those electrolytes having aqueous solution as good conductor, the solutions that ionize completely are known as strong electrolytes. The solution which does not ionizes completely and has aqueous solution as poor conductor is known as weak electrolyte.

Interpretation Introduction

(c)

Interpretation:

Whether ${\text{K}}_2{\text{SO}}_4\left(aq\right)$, a strong or a weak electrolyte is to be stated.

Concept introduction:

The electrolytes whose aqueous solution is a good conductor, and the complete ionization takes place in the solution are known as strong electrolytes. The solutions in which no or partial ionization takes place are weak electrolytes, their aqueous solution is a poor conductor.

Interpretation Introduction

(d)

Interpretation:

Whether ${\text{PbI}}_2\left(s\right)$, a strong or weak electrolyte is to be stated.

Concept introduction:

The strong electrolytes are those electrolytes having aqueous solution as good conductor, the solutions that ionize completely are known as strong electrolytes. The solution which does not ionizes completely and has aqueous solution as poor conductor is known as weak electrolyte.
