25.0\,\text{mL}

sample of

0.0050\,\text{M}

\mathrm{MgCl_2}

is diluted to

1.00\,\text{L}

with deionized water. The solubility product of

\mathrm{Mg(OH)_2}

25\,^\circ\text{C}

K_{\text{sp}}=1.8\times10^{-11}

. Calculate the pH at which

\mathrm{Mg(OH)_2}

will just begin to precipitate from the resulting solution.
