(a) Will \( \mathrm{Mg}(\mathrm{OH})_{2} \) precipitate from a solution that is \( 0.01 \mathrm{M} \) in \( \mathrm{MgCl}_{2} \) and also \( 0.10 \mathrm{M} \) in \( \mathrm{NH}_{3} \).
(b) What \( \mathrm{NH}_{4}^{+} \)must maintained to prevent the precipitation of \( \mathrm{Mg}(\mathrm{OH})_{2} \) from a solution that is \( 0.010 \mathrm{MgCl}_{2} \) in \( 0.1 \mathrm{MNH}_{3} \mathrm{~K}_{\text {sp }} \mathrm{Mg}(\mathrm{OH})_{2}=2.5 \times 10^{-11}, \mathrm{~K}_{\mathrm{b}} \mathrm{NH}_{3}=1.8 \times 10^{-5} \)
