10 L of a saturated solution of calcium fluoride, CaF2, was evaporated and found to contain 4.28 millimoles (mmol) fluoride. What is the value of Ksp?
CaF2(s) -> <- ca2+ (aq) +2 F- (aq)
How did
Ksp= [Ca2+] [F-]2
become Ksp= [s] [2s]2= 4s3
Cause I thought it was only Ksp= [s] [s]2 = s3
and why 4.28x10-3 have to devide by 10
and why the
[F-] = 4.28 x 10-4 have to eqautes to 2 to have s= 2.14x10-4 M

17. Calculate the solubility of calcium fluoride in a 0.035 M sodium fluoride solution. Some important information is given below: ▪ NaF will ionize completely, and the reaction is: NaF (aq) → Na+ (aq) + F− (aq) ▪ The calcium fluoride equilibrium reaction is: CaF2 (s) → Ca+2 (aq) + 2F−1 (aq) ▪ For CaF2 (s), Ksp is 4.0 × 10−11 ▪ Na+ (aq) is a spectator ion; The F− (aq) is the common ion.

Calcium fluoride, CaF2, is an insoluble salt (Ksp = 1.46 x 10-10) that can be formed by precipitation by mixing solutions of calcium nitrate and sodium fluoride. Suppose 200.0 mL of a 0.600 M Ca(NO3)2(aq) solution are mixed with 400.0 mL of a 0.0600 M NaF(aq) solution. Will a precipitate form? How much calcium fluoride could form?
