Chapter 23, Problem 42QP

Interpretation Introduction

Interpretation:

The increasing order of solubility of the sulfates in water of the second group metals is to be listed and its trend of order is to be explained.

Concept introduction:

Sulfates are inorganic ions that are both, found in nature and synthesized for the industry.

Generally, the solubility of sulfates decreases down the groups.

The compounds ${\text{BeSO}}_{\text{4}}$

and ${\text{MgSO}}_{\text{4}}$, are highly soluble. The compound ${\text{CaSO}}_{\text{4}}$

is sparingly soluble, but the sulfates of $\text{Sr}$, $\text{Ba}$, and $\text{Ra}$

seem to be insoluble.
