Answer 1

The heat energy released when new bonds are made between the ions and water molecules is known as thehydration enthalpy of the ion.



Thehydration enthalpy is the enthalpychange when 1 mole of gaseous ions dissolve in sufficient water to give an infinitely dilute solution. 


Hydration enthalpies are always negative.
