Question

Consider the following data for questions 1-6: Two solutions of an unknown slightly soluble salt, A(OH)2, were allowed to equilibriate- one at 25 degrees celsius and the other at 80 degrees celsius. A 15.00 mL- aliquor of each solution is titrated with 0.200 M HCl. 8.00 mL of the acid is required to reach the endpoint of the titration at 25 degrees celsius, while 69.15 mL are required for the 80 degrees celsius solution.

1. Calculate the Ksp at 25 degrees celsius.

2. calculate the Ksp at 80 degrees celsius.

3. calculate the Gibbs free energy (in Kj/mol) at 25 degree celcius.

4. calculate the Gibbs free energy (in Kj/mol) at 80 degrees celsius.
