Chemistry - Ionic Equilibrium Question with Solution | TestHub

At $25^{\circ }\mathrm{C}$, in a $10^{-4}\mathrm{M}$ solution of $\mathrm{Mg}{\left({\mathrm{NO}}_3\right)}_2$ if pH of the solution is adjusted, at what minimum value of $\mathrm{pH}\mathrm{Mg}(\mathrm{OH}{)}_2$ will start precipitating? ${\mathrm{K}}_{\mathrm{sp}}\left[\mathrm{Mg}(\mathrm{OH}{)}_2\right]=10^{-11}{\mathrm{M}}^3$.
