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