Chapter 17, Problem 65A

Why are compounds such as sodium chloride usually not given $K_{\text{sp }}$ values?

Interpretation Introduction

Interpretation:

Some compounds are not given ${\text{K}}_{\text{sp}}$ values, the reason behind which is to be explained.

Concept introduction:

The solubility product is calculated for the ionic compounds which are either sparingly soluble or insoluble in water.

Answer to Problem 65A

$\text{NaCl}$ is a soluble compound and soluble compounds does not give $\text{Ksp}$ values.

Explanation of Solution

By dissolving sodium chloride in water, a saturated solution of sodium chloride is formed. Sodium chloride completely dissociates into sodium and chloride ions. Thus, solubility product cannot be calculated for it or it has ionic product.

$\text{ NaCl}{\to }_{}{\text{Na}}^{\text{+}}{\text{+ Cl}}^{\text{-}}$
