The solubility product of strontium fluoride in water is Ks =4.33·10-9 at 25°C.

a. Calculate the molar solubility of a saturated strontium fluoridesolution assuming that you have an ideal solution and that allnon-dissociated strontium fluoride is a pure solid phase.

b. Calculate the activity coefficient ?± of the ions in yourstrontium fluoride solution (by iteration; convergence to threesignificant digits) and the final concentration of Sr2+.

c. Calculate the Gibbs Energy of formation of strontium fluorideusing the solubility product as well as the Gibbs energies offormation of Sr2+(aq) and F- (aq) at 25°C: ?G(Sr2+, aq) = -559.5kJ/mol, ?G(F- , aq) = - 278.8 kJ/mol.
