Two solutions of an unknown slightly soluble salt, A(OH)2, were allowed to equilibriate- one at 25 degrees C, the other at 80 degrees C. A 15 mL aliquot of each solution is tiotrated with .200 M HCl. 8 mL of the acid is required to reach the endpoint of the titration at 25 degrees C, while 69.15 mL are required for the 80 degrees C solution.

1) Calculate the Kspa+ at 25 degrres C.
2) Calculate the Ksp at 80 degrees C.
