Chapter 15, Problem 106E

Interpretation Introduction

Interpretation: The minimum mass of ${\text{Na}}_2{\text{SO}}_4$ that is required to form a precipitate is to be calculated.

Concept Introduction: The chemical equation which occurs at equilibrium represents the dissolving of an ionic compound is termed as solubility product constant $\left(K_{\text{sp}}\right)$.

The solubility of the compound can be measured with the help of $K_{\text{sp}}$.

If value of $K_{\text{sp}}$ is large, it indicates that compound is very soluble.

If value of $K_{\text{sp}}$ is small, it indicates that compound is not very soluble.

The units of molar solubility $\left(s\right)$ is moles per liter $\left(\text{mol}/\text{L}\right)$.

The precipitation will take place when ionic product exceeds the solubility product constant.
