The solubility of an ionic compound can be described quantitatively by a value called the solubility product constant, $K_{\mathrm{sp}} .$ For the general process $\mathrm{A}_{a} \mathrm{B}_{b} \rightleftharpoons a \mathrm{A}^{n+}+b \mathrm{B}^{m-}$ $K_{\mathrm{sp}}=\left[\mathrm{A}^{n+}\right]^{a}\left[\mathrm{B}^{m-}\right]^{b} .$ The brackets refer to concentrations in moles per liter. (a) Write the expression for the solubility product constant of $\mathrm{Ag}_{2} \mathrm{CrO}_{4}$ . (b) If $K_{\text { sp }}=1.1 \times 10^{-12}$ for $A g_{2} \mathrm{CrO}_{4},$ what are the molar concentrations of $A g^{+}$ and $C r O_{4}^{2-}$ in a saturated solution?
The value of $K_{\mathrm{sp}}$ for $\mathrm{PbCrO}_{4}(s)$ in equilibrium with water at $25^{\circ} \mathrm{C}$ is $2.8 \times 10^{-13} \mathrm{M}^{2}$. Write the chemical equation that represents the solubility equilibrium for $\mathrm{PbCrO}_{4}(s)$ and calculate its solubility in grams per liter in water at $25^{\circ} \mathrm{C}$.
Calculate the solubility product constant $K_{\mathrm{sp}}$ for each of the following, based on the solubility information provided. a. BaSO $_{4}=2.4 \times 10^{-4} \mathrm{g} / 100 . \mathrm{g} \mathrm{H}_{2} \mathrm{O}$ at $20^{\circ} \mathrm{C}$ b. $\mathrm{Ca}(\mathrm{OH})_{2}=0.173 \mathrm{g} / 100 . \mathrm{g} \mathrm{H}_{2} \mathrm{O}$ at $20^{\circ} \mathrm{C}$
