Vedclass · Answer

(B) The heat of neutralisation for a strong acid and a strong base is constant (approximately $-57.1 \ kJ \ mol^{-1}$) because both are completely dissociated in aqueous solution. Therefore,the net chemical reaction in every such case is simply the combination of hydrogen ions and hydroxide ions to form water: $H^{+}(aq) + OH^{-}(aq) \rightarrow H_2O(l)$.

The heat of neutralisation of a strong acid by a strong base is a constant value because
