Chapter 17, Problem 38PS

a)

Interpretation Introduction

Interpretation:

The two insoluble salts of ${\text{SO}}_{\text{4}}^{\text{2-}}$ has to be named.

Concept Introduction:

Precipitation reactions are exchange reactions in which one of the products is a water - insoluble compounds.

For example -${\text{CaCO}}_{\text{3}}$

  ${\text{CaCl}}_{\text{2}}{\text{(aq) + Na}}_{\text{2}}{\text{CO}}_{\text{3}}\text{(aq) }\to {\text{ CaCO}}_{\text{3}}\text{(s) + 2NaCl(aq)}$

The solubility of a compound is defined as the amount of that substance that can be dissolved in a given quantity of a solvent.
