Chapter 17, Problem 17.102SP

Interpretation Introduction

(a)

Interpretation:

The value of $K_{\text{sp}}$ for ${\text{Ca}}_3{\left({\text{PO}}_{\text{4}}\right)}_{\text{2}}$ is to be calculated.

Concept introduction:

Solubility product is equilibrium constant for reaction that occurs when an ionic compound is dissolved to produce its constituent ions. It is represented by $K_{\text{sp}}$. Consider ${\text{A}}_x{\text{B}}_y$ to be an ionic compound. Its dissociation occurs as follows:

${\text{A}}_x{\text{B}}_y\rightleftharpoons x{\text{A}}^{y+}+y{\text{A}}^{x-}$

The expression for its $K_{\text{sp}}$ is as follows:

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

(b)

Interpretation:

The value of $\left[{\text{Ca}}^{2+}\right]$ in ${\text{Ca}}_3{\left({\text{PO}}_{\text{4}}\right)}_{\text{2}}$ is to be calculated.
