Solubility, Ion Size, and HSAB

The effects of solvation and solubility can also be explored using thermodynamic calcula- 

If the enthalpy changes of any three of the four reactions can be determined, the fourth enthalpy change can be found by completing the cycle The solvation effects of many ions have been estimated by comparing similar measurements on different compounds. The entropy of solvation needs to be included to calculate the free energy change associated with dissolution.
