Chapter 15, Problem 42E

Interpretation Introduction

Interpretation: The solubility product of ${\text{Pb}}_{\text{3}}{\left({\text{PO}}_{\text{4}}\right)}_{\text{2}}$ is given. The solubility of ${\text{Pb}}_{\text{3}}{\left({\text{PO}}_{\text{4}}\right)}_{\text{2}}$ is to be calculated in a given concentration of $\text{Pb}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$.

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 as,

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

Where,

• $x$ is coefficient of concentration of $\text{A}$.
• $y$ is coefficient of concentration of $\text{B}$.
