If 15.0 mL of 7.25Ã10-4 M MgI2 are added to 22.0 mL of 1.80Ã10-5 M KF, will solid MgF2 (Ksp = 6.4Ã10-9) precipitate? _____yes/no
If a precipitate will not form, what fluoride ion concentration will cause a precipitate of magnesium fluoride to form? If a precipitate will form, what is the minimum [F-] that could have been present without initiating precipitation? Assume the total volume used in the above example.
