Q: The Ksp of CaF2 is 3.9 × 10?11. Calculate the molarsolubility of CaF2 in water.
Detail of solution and answer is needed to better understand,thanks.
*This already given but I have some doubt in the way thesolution is given as below: Can there be a clearer solution tobetter undestand.?
. . .CaF2 <---> Ca++ + 2F-
I. . . . . . . . . . . . . .0. . . .. . 0
E. . . . . . . . . . .. s. . . .. .2s
ksp = [Ca++][F-]^2
3.9x10^-11 = s(2s)^2
4s^3 = 3.9x10^-11
s = [CaF2] = 0.000214 moles / L (78.1 g / mol CaF2) = 0.0167 g/LCaF2
