∆H2 is heat of neutralisation since heat of neutralisation is same for all strong acid and base (-57.62kJ/mol at 25°C) as in all cases H+ ion and OH- ions combine to give H2O. if heat of formation of H2O is equal to heat of neutralisation ( which is not actually so) then heat of formation of NaCl will be equal to heat of neutralisation
