1. What is the saturated [Al3+] concentration at pH7 made by the addition of AlCl3 to distilled water?
2. AlCl3<-->Al3++3Cl-
3H2O<-->3H++3OH- Kw=1x10-14
Al3++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.
