ANTIMONATE

n.?m’o%n-at. Lat., an tim on i as, stibias. Fr., antimoniate. Ger., An tim on i at. It., Sp., an tim on i a to. A salt of antimonic acid, a compound of antimony pentoxide with the oxide of another element or radicle. The normal or neutral a's, met antimonates, or a’s proper, have the constitution M(SbOg) or M,0n(Sb,Og)a where M is a radicle the quantivalence of which is n. The acid a’s, or biantimonates, are compounds of a metallic oxide with a double molecule of antimony pentoxide or compounds of a double molecule of a normal a. with a single molecule of antimony pentoxide: M,On.2nSb20, or nSb,O5.2M(SbOg}a. The ortho antimonates, formed either from antimonic or from ortho antimonic acid, have the general formula M’H,SbO, (dihydric or monometallic o's), M’” HSbO, (monohydric or dimetallic 0's), or M”’SbO4 (normal.
