Answer:

So far as I know, #"hydration energy"#...........

Explanation:

So far as I know, #"hydration energy"# is the energy associated with the formation of one mole of aquated ions from one mole of gaeous cations (or anions).......

#M^(n+)(g) + H_2O(l) rarr [M(OH_2)_(4-6)]^(n+)+Delta#....

Where #Delta_"rxn"-="hydration energy"#

This is certainly measurable for a given series of CATIONS (if we keep the anion constant....) and hydration energy increase by an inverse proportion to the size of the ion.....
