Chemistry - Ionic Equilibrium Question with Solution | TestHub

$\mathrm{ApBq}\rightleftharpoons {\mathrm{pA}}_{\mathrm{Sp}}^{+}+{\mathrm{qB}}_{\mathrm{Sq}}$ Let the solubility be $\mathrm{S}\mathrm{mol}/$ liter Thus, \begin{aligned} \mathrm{K}_{\mathrm{sp}} &=\left[\mathrm{A}^{+}\right]^{\mathrm{p}}\left[\mathrm{B}^{-}\right]^{\mathrm{q}} \\ &=[\mathrm{Sp}]^{\mathrm{p}}[\mathrm{Sq}]^{\mathrm{q}}=\mathrm{p}^{\mathrm{p} \cdot} \mathrm{q}^{\mathrm{q}}(\mathrm{S})^{\mathrm{p}+\mathrm{q}} \end{aligned}
