A neutralization reaction (a chemical reaction in which an acid and a base react in stoichiometric amounts to produce water and a salt) is one in which an acid and a base react in stoichiometric amounts to produce water and a salt (the general term for any ionic substance that does not have OH − as the anion or H + as the cation). The reaction equation between ammonia (NH3) and hydrochloric acid (HCl) is written as follows: NH3+HCl=NH4Cl. Ammonium chloride is made up of NH 4 + cations from the base ( NH 3) and Cl − anions from the acid ( HCl). For reactions involving acetic acid or ammonia, the measured enthalpy change of neutralization is a few kJ less exothermic than with strong acids and bases. The molar enthalpy of neutralisation between hydrochloric acid and ammonia solution was found to be -52.2 kj mol4, while that of hydrochloric acid and sodium hydroxide was 57.1 kJ mol-1.
