There is a large difference between delta H of dissolution of an anhydrous salt dissolved in water anddelta H of dissolution of the hydrated form of the same salt dissolved in water. How do the enthalpy of dissolution, the crystal lattice energy, and the solvation energy of the two salts relate to these experimental observations?

Proceeds at a certain temperature until the partial pressures of H2O, H2, and O2 reach 0.0800 atm, 0.00500 atm, and 0.00200 atm respectively.
An old bottle of HCl was taken from the stockroom and a titration analysis was performed on it. The bottle of this acid lost its label years ago so the molarity was unknown.
