Chapter 3, Problem 26QRT

(a)

Interpretation Introduction

Interpretation:

The ions present in the aqueous solution of ${\text{CaI}}_{\text{2}}$ has to be identified.

Concept introduction:

Dissociation:

When ionic compound dissolved in water it produced cation and anion, this process is called as dissociation.

Generally the ionic compound consists of cation and anion.

Cation: When electrons are removed from the atom that results to form positively charged ion called cation.

Anion: Addition of electron to atom results to form negatively charged ion called anion.
