    Q#1 (Common ion problem)
    What is the solubility,in mg/mL of BaF2 in
    a)Pure Water
    b)in a solution containing 5.0mg/mL of KF
    Ksp of BaF2=1.0*10^-6

    Q#2 Effect of pH on solubility
    a)Calculate the solubility of a saturated solution og Mg(OH)2 on pure water.(My answer is 1.65096*10^-4M
    b)Calculate the solubility of the same saturated solution of Mg(OH)2 in a solution with pH of 10.49.
    Mg(OH)2 Ksp= 1.8*10^-11

    Q#1 (Common ion problem)
    What is the solubility,in mg/mL of BaF2 in
    a)Pure Water
    b)in a solution containing 5.0mg/mL of KF
    Ksp of BaF2=1.0*10^-6

    For this question, you will have to write both the (1) reaction equation for the important solid dissolving (BaF2):
    BaF2 (s)  Ba2+ + 2F-
    -s s 2s

    So we can see that if s amount of BaF2 dissolves, we will have s amount of barium ions and 2s amount of fluoride ions. But in this ...
