Consider a saturated solution of MgF2 with excess solid MgF2. Calculate the molar solubility of MgF2 (a) at pH 7.00 (b) at pH 2.00?

MgF2 <--> Mg(2+) + 2F(-)
F(-) + H2O <--> HF + OH-
. . . Need Ka for HF and Kw
use those with ... pH = 7.00 >>> [H+] = 1x10^-7M
b. use with pH = 2.00 >>> [H+] = 1x10^-2 M
