Stoichiometry
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 salt formed does not hydrolyse

The strong base and strong acid reacts completely

The strong base and strong acid reacts in aqueous solution

Only OH⁻ and H⁺ ions react in every case
