     Note: Except in case of ammonium salts, accurately speaking,

           the case of diacid and triacid bases, and of dibasic
           and tribasic acids, the mutual neutralization may vary
           in degree, producing respectively basic, neutral, or
           acid salts. See Phrases below.
