Chapter 4, Problem 4.5P

(a)

Interpretation Introduction

Interpretation:

The best following scene among them that represent the ions present in an aqueous solution of ${\text{CaCl}}_2$ is to be identified.

Concept introduction:

A solution is a combination of two parts: solute and solvent. A solute is the substance that is present in small quantity and solvent is the substance in which solute is dissolved. When water acts as a solvent then it is known as an aqueous solution.

Ionic compounds are the compounds that are composed of charged ions. There are held together by electrostatic forces. Ionic compounds dissociate into ions when dissolved in water. ${\text{CaCl}}_2$, ${\text{Li}}_2{\text{SO}}_4$ and ${\text{NH}}_4\text{Br}$ are the examples of an ionic compound.
