The average enthalpy of neutralization of any strong acid by a strong base is found to be - 57.7 kJ (-13.7 kcal) irrespective of the nature of acid or the base. This suggests that the net chemical reaction in all neutralization reactions is the same, viz.
This is because strong acids and strong bases are completely ionized in aqueous solutions. The aqueous solution of one gram equivalent of all strong acids contains the same number of H+ ions.
