The Ksp for CaF2 is 3.9 x 10-11 at 25oC. What is the solubility?
nevsk [136]

We have to know the solubility of CaF₂.

The solubility of CaF₂ is: (c) 2.1 x 10-4 Molar

The general expression of solubility product of any sparingly soluble salt (having solubility S) with formula A_{x} B_{y} is: x^{x} y^{y} S^{x+y}.

For the compound, CaF₂, x=1, y=2 So, K_{sp}=1^{1}2^{2}S^{1+2}=4S³= 3.9 x 10-11  (Given)

S³=\frac{3.9 X 10^{-11} }{4}

S³=9.75  X 10^{-12}

S= 2.1 X 10^{-4} Molar
