Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because
the strong base and strong acid reacts completely.
the salt formed does not hydrolyse.
only OH- and H+ ions react in every case.
the strong base and strong acid reacts in aqueous solution.
