BASE

n, Bas. Gr., Béots. Lat., basis. Fr., base. Ger., Grund, Grundlage, Grundfläche, Base, 1. In general, the underlying’ fundamental, or lower portion of a structure. 2. In chemistry, according to the old theories of the dual nature of salts, the electropositive constituent of the latter, i. ¢., the metallic oxide or other substance which, by union with the electro-negative (acid) constituent, formed the salt. It may be defined as a compound formed either upon the water type (oxide, hydrate, or sulpho-salt) or pcs the ammonia type (ammonia, amine, alkaloid, phosphine, stibine, arsine, and bismuthine) capable of neutralizing acids and combining with both acids and anhydrides, In the case of the first cla of b's (those derived from the water type), the combination is effected by double decomposition, the b. lo: acid its hydrogen. In the case of b's formed upon the ammonia type, the combination is effected by direct union without decomposition, See AMMONIA and AMMONIUM. B’s are called monacid, diacld, or triacid, according as their acidity (their eapacity for saturating acids) is 1, 2, or 3, à. e., according as they neutralize 1, 2. or 3 molecules of a monobasic acid. The b’s formed upon the water type are designated as monohydric, dihydric, or trihydric, according as they contain 1, 2, or 3 molecules of hydroxy! or hydrosulphanyl. [B.] 3.
