Hydration enthalpy consists only one ion-dipole attraction between oxygen atoms. This happens only with positive ions. But with negative ions ion-dipole attraction is formed between negative ions and positive hydrogens.

Rajiv, I guess there is one single factor that can affect the hydration enthalpy. That is it is governed by attraction between ions and water molecules.

Jeff you are completely right. Attraction between ions and water molecules can affect the hydration enthalpy. The attraction is smaller ion and vice-versa.
