5. In a saturated solution of MgF2 at 18C , the concentration of Mg2+ is 1.21 x 10-3 molar. The equilibrium is represented by the equation below

MgF2(s) ---> Mg2+ (aq) + 2F- (aq)

A) write the expression for the solubility product , Ksp , and calculate its value at 18C

B) predict whether a precipitate of MgF2 will form when 100.0 mls of 3.00 x 10-3 molar Mg(NO3)2 solution is mixed with 200.0 mls of a 2.00 x 10-3 molar NaF solution at 18C.
