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