Chapter 4, Problem 6QP

Interpretation Introduction

Interpretation:

The aqueous solutions of three compounds, as shown in the diagram, are to be identified as nonelectrolyte, weak electrolyte, or strong electrolyte.

Concept introduction:

The process by which a compound produces ions in a solution upon dissolution is called dissociation.

An electrolyte is a substance that dissociates to produce ions when dissolved in water. Due to the formation of ions, electrolytes can conduct electricity.

A nonelectrolyte isa substance that does not dissociate to produce ions. Hence, they cannot conduct electricity.

The two types of electrolytes are strong and weak. The strong electrolytes completely dissociate into their constituent ions upon dissolution. Thus, they are good conductors of electricity.

The weak electrolytes do not dissociate completely upon dissolution. The solution of a weak electrolyte contains very few ionsand unionized molecules predominantly. Hence, conducts less electricity.
