a. The concentration solubility product of \(\mathrm{Al}(\mathrm{OH})_{3}\) is \(1.1 \times 10^{-15}(\mathrm{~mol} / \mathrm{L})^{4}\) (Mullin, 2001). At saturation, what is the concentration of \(\mathrm{Al}(\mathrm{OH})_{3}\) ? Note: This requires some thought. How much of each ion is there in the solution?

b. Repeat part a, but use the value of \(3.70 \times 10^{-15}(\mathrm{~mol} / \mathrm{L})^{4}\) (Scholl and Myerson, 2019),
