Chapter 3, Problem 8PP

Interpretation Introduction

Interpretation:

The compounds of ${\text{Cr}}_2{\text{S}}_{\text{3}}$ and ${\text{FeSO}}_3$ are to be named.

Concept Introduction:

The rules that are used for naming the ionic compounds which are as follows:

The cation is written first, followed by the anion.

Based on the position of element in the periodic table, analyze the charge on cation and anion.

Arrange the subscript of cation and anion in the compound in such a way that the compound should be electrically neutral, which means that the charge of cation and anion should be balanced and give a net zero charge.
