difference between solvation enthalpy and hydration enthalpy?
Dear Student,
1.Enthalpy of hydration is the amount of heat evolved when one mole of an ion dissolves in water .while enthalpy of solvation is the energy change when 1 mole of any ionic solid dissolves in any solvent .
2. Enthalpy of hydration is always negative but enthalpy of solvation may be positive or negative.
Regards!
