Chapter 5, Problem 5.1KSP

Interpretation Introduction

Interpretation:

The correct name of ${\text{CaSO}}_{\text{4}}$ has to be given.

Concept Introduction:

In the formula of chemical compound, the sum of the charge of cation and anion must be equal to zero. The ration of cation and anion should be known in order to deduce the formula of a compound.

Rules for Nomenclature of ionic compounds:

• The name of the cation should be followed by the name of anion.

Cation: Removal of electron from the atom results to form positively charged ion called cation.

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

The net charge present in the element denotes the presence or absence of electrons in the element.
