Chapter 18, Problem 69A

Interpretation Introduction

Interpretation: The explanation for what the solubility product constant $\left({\text{K}}_{\text{sp}}\right)$ represent is to be stated.

Concept Introduction: The expression representing the product of the concentrations of the ions each raised to the power (equal to their stoichiometric coefficient) in the dissociation equation is termed as solubility product constant $\left({\text{K}}_{\text{sp}}\right)$ .

Answer to Problem 69A

The solubility product constant $\left({\text{K}}_{\text{sp}}\right)$ represents whether a compound is soluble, most soluble, or least soluble.

Explanation of Solution

The smaller the value of the solubility product constant $\left({\text{K}}_{\text{sp}}\right)$ , the lower the solubility of the compound. On the other hand, the larger the value of the solubility product constant $\left({\text{K}}_{\text{sp}}\right)$ , the higher the solubility of the compound. That means the solubility product constant $\left({\text{K}}_{\text{sp}}\right)$ represents whether a compound is soluble, most soluble, or least soluble.
