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 in aqueous solution Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts completely The salt formed does not hydrolyse The strong base and strong acid reacts in aqueous solution Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts completely ANSWER DOWNLOAD EXAMIANS APP
