Dear Student
Enthalpy---Enthalpy is the measure of the total energy of a system. 
Ionization enthalpy---heat evolved when any atom get ionized is called inonization enthalpy:
Enthalpy of dissociation-----The enthalpy change when ONE MOLE of an ionic lattice dissociates into isolated gaseous ions.
Hydration enthalpy----Hydration enthalpy of an ion is the amount of energy released when a mole of the ion dissolves in a large amount of water forming an infinite dilute solution in the process.
We hope that clarifies your query.
