Consider the solubility of solid magnesium hydoxide, Mg(OH)2 in water for which the solubility equilibrium is:
Mg(OH)2 (s) <---> Mg 2+ (aq) + 2OH- (aq)
A saturated solution of Mg(OH)2 is prepared and allowed to equilibriate at 25 degrees celcius. A 25.00 mL sample of the 25 degrees celcius solution is titrated with 0.00508M HCL solution. 1.38 mL of the HCL solution are required to fully react the solution sample.
a). determine the molar solubility of Mg(OH)2 at 25 degrees celcius
b). calculate Ksp for Mg(OH)2 in water at 25 degrees celcius
c). calculate delta G for Mg(OH)2 dissolving in water at 25 degrees celcius
d). what additional experimental measurements would be required in order to determine delta H and delta S for Mg(OH)2 dissolving in water
