**1. What is the saturated [Al3+] concentration at pH7 made by the addition of AlCl3 to distilled water?**

**2. AlCl**

3H

Al

_{3}<-->Al^{3+}+3Cl-3H

_{2}O<-->3H^{+}+3OH- Kw=1x10^{-14}Al

^{3+}+3OH-<-->Al(OH)_{3}Ksp=3x10^{-34}**3. I'm familiar with this type of problem, but not the way in which it's being asked. I hope I have included the equations and constants that are pertinent below. I would start by taking the Ksp for the precipitate and mulitplying it by 1/Kw. This multiplied by the solubility product for AlCl3 should give the equilibrium product for the whole equation, but I don't know how to get that.**
