Chapter 5, Problem 65E

Interpretation Introduction

Interpretation:

Each of the given ionic compounds that contains a polyatomic ion is to be named.

Concept introduction:

Polyatomic ions, that is, group of atoms carrying a charge also form ionic compounds. Polyatomic ions may be a cation like ammonium ion ${\text{NH}}_{\text{4}}^{\text{+}}$ or anion like nitrate ion ${\text{NO}}_{\text{3}}^{\text{-}}$.

In order to name the ionic compounds that contain a polyatomic ion, use the name of the polyatomic ion as it is.

The naming of such ionic compounds that contain a polyatomic ion is as follows:

Cation (charge of cation in Roman numeral in parentheses) + polyatomic anion name

If the compound contains both a polyatomic cation and a polyatomic anion, use the names of both polyatomic ions.
