Chapter 17, Problem 17.21P

Interpretation Introduction

Interpretation:

The $K_{\text{sp}}$ of ${\text{Ca}}_{\text{3}}{\left({\text{PO}}_{\text{4}}\right)}_{\text{2}}$ needs to be determined.

Concept introduction:

In general, $K_{\text{sp}}$ is the product of its dissolved ion concentration raised to intensity of their stoichiometric coefficients.

$\begin{array}{l}{\text{M}}_{\text{y}}{\text{X}}_{\text{z}}\left(\text{s}\right)\rightleftharpoons {\text{yM}}^{\text{z+}}{\text{+zX}}^{y-}\\ K_{\text{sp}}={\left[{\text{M}}^{\text{z+}}\right]}^y{\left[{\text{X}}^{y-}\right]}^z\end{array}$

Here, $K_{\text{sp}}$ represents solubility product constant, $\left[{\text{M}}^{\text{z+}}\right]$ and $\left[{\text{X}}^{y-}\right]$ represents molar solubility of ions.
