what is the concentration of all the dissolved constituents in a saturated solution of CaF2 whose pH is "Magically" fixed at 9.25?
CaF2 Ca2+ + 2F-
Ksp of CaF2 = [Ca2+] [F-]2
Ksp of CaF2 = 3.910-11 = (s) (2s)2 = 4s3
Therefore, s = 2.110-4mol/L
s = 2.110-4mol/L is the concentration of Ca2+
For [F-], it is 2s. Therefore, 2s = [F-] = 4.210-4 mol/L
