Standard Free energy of hydration

Post by César Vásquez »

If there are six water molecules in the inner-sphere hydration shells of both Na+ and Al3+, how much of the standard free energy of hydration can be accounted for by inner-sphere hydration?

Standard Free energy of hydration, Delta G=-164\ z^2 +1.3\{kcal}{mole};
r’cation = cation radius + 0.72 Å
r’anion = anion radius + 0.3-0.6 Å
z is the charge of the ion

Does anyone have an example of how to solve this problem?
