WebFor reactions involving acetic acid or ammonia, the measured enthalpy change of neutralization is a few kJ less exothermic than with strong acids and bases. For example, one source which gives the enthalpy change of neutralization of sodium hydroxide solution with HCl as -57 kJ mol-1: NaOH(aq)+HCl(aq)→Na+(aq)+Cl−(aq)+H2O(l) WebIn chemistry and thermodynamics, the enthalpy of neutralization ( ΔHn) is the change in enthalpy that occurs when one equivalent of an acid and a base undergo a neutralization reaction to form water and a salt. It is a special case of the enthalpy of reaction. It is defined as the energy released with the formation of 1 mole of water.
