Chapter 9, Problem 2ECE

Interpretation Introduction

(a)

Interpretation:

The classification of ${\text{Na}}_{\text{2}}\text{S}$ as a strong electrolyte, a weak electrolyte, or a nonelectrolyte is to be stated.

Concept introduction:

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

Interpretation Introduction

(b)

Interpretation:

The major species in the aqueous solution of ${\text{Na}}_{\text{2}}\text{S}$ is to be identified.

Concept introduction:

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

Interpretation Introduction

(c)

Interpretation:

The minor species in the aqueous solution of ${\text{Na}}_{\text{2}}\text{S}$ is to be identified.

Concept introduction:

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