4 The acid-base reactions in non-aqueous solution can also be regarded as proton-transfer reactions.Example: the formation reaction of NHCl: H+ HCI NH- NH acid(1) base(2) acid(2) base(1) the neutralization reaction in liquid ammonia H NH CI+NaNH 2NH+NaCl acid(1) base(2) acid(2)+base(1) ④ The acid-base reactions in non-aqueous solution can also be regarded as proton-transfer reactions.
