Chapter 15, Problem 79E

Interpretation Introduction

Interpretation:

The correct solubility product $\left({\text{K}}_{\text{sp}}\right)$ expression is to be determined with help of concentration of ions dissolves in the solvent for ${\text{Fe(OH)}}_2$.

Concept Introduction:

The solubility product $\left({\text{K}}_{\text{sp}}\right)$ expression for any compound is the mathematical product of the concentration of their constituent ions raised to the power of their stoichiometric coefficient.

The solubility of compound decreases if compound contains same ion that already present in the solvent.

Solubility product has unit of concentration.

For the given chemical equation $\text{A + B }\to \text{ C +}\text{}\text{D}$, the solubility product is given by ${\text{K}}_{\text{sp}}\text{ = }\left[\text{C}\right]\left[\text{D}\right]$.
