What is the solubility product of \( \mathrm{Al}(\mathrm{OH})_{3} \) in water?
P given:

W
\[
\begin{array}{l}
\mathrm{Al}(\mathrm{OH})_{4}{ }^{-}(\mathrm{aq}) \rightleftharpoons \mathrm{Al}^{3+}(\mathrm{aq})+4 \mathrm{OH}^{-}(\mathrm{aq}) \\
\mathrm{K}=1.3 \times 10^{-34} \\
\mathrm{Al}(\mathrm{OH})_{3}(\mathrm{~s})+\mathrm{OH}^{-}(\mathrm{aq}) \rightleftharpoons \mathrm{Al}(\mathrm{OH})_{4}^{-}(\mathrm{aq}) \\
\mathrm{K}=38.5
\end{array}
\]
(1) \( 3.1 \times 10^{-35} \)
(2) \( 5 \times 10^{-33} \)
(3) \( 6.1 \times 10^{-33} \)
(4) \( 5 \times 10^{-34} \)
