Chapter 15, Problem 92AE

Interpretation Introduction

Interpretation: The equilibrium concentration of $\left[{\text{Mg}}^{\text{2+}}\right]$ and $\left[{\text{F}}^{-}\right]$ is to be calculated.

Concept introduction: Solubility is defined as the maximum amount of solute that can dissolve at a certain amount of solvent at certain temperature. The solubility product, $K_{\text{sp}}$ is the equilibrium constant that is applied when salt partially dissolve in a solvent. The solubility product of dissociation of ${\text{A}}_x{\text{B}}_y$ is calculated by the formula,

$K_{\text{sp}}={\left[\text{A}\right]}^x{\left[\text{B}\right]}^y$
