a) the ksp for Al(OH)3 is 1.9*10^-33. what is the pH of a sauturated solution of Al(OH)3. ignore any hydrolysis
b)An aqueous solution contains 0.01M F- and 0.01M So4 2-. solid bacl2 is added at constant volume. which will precipitate first BaF2 (ksp= 1.7*10^-6) or Baso4 (Ksp=1.08*10^-10)? if the Ba2+ concentration is adjusted to 0.05M, what are the molar concentrations of F1- and So4 2- remaining in the solution?
