ARS ENAMINE

n. A?r-se’n’a?m-en, Hydrogen arsenide. ARSENATE, n. A‘r’se%n-at, Written also arseniate. Lat., arsenas, arsenias. Fr., arséniate. Ger., arsensaures Salz, Arsenat. It., Sp., arseniato. A salt of arsenic (ortho arsenic) acid.. The normal a’s or tri arsenates have the formula R(AsO,) where R is a trivalent radicle, or Ra(AsO«)n where R is a radicle of the quantivalence ofn. The acid,or ric, as include (1) the dimetallic or monohydrie a's, of the general formula R’’HAsO, or Ro(HASO,)n, and (2) the monometallic or dyhydric a’s, or bin arseniates, of the general formula R(H,AsO,)a, where R” is a bivalent radicle and R a radicle of the quantivalence of n. Basic a’s, composed of arsenic acid combined with the oxide or hydrate of a base, are also known. The term basie a. was formerly applied to the normal a’s. {By See also MET ARSENATE and PYRO ARSENATE, and for the individual a’s see under the names of the bases.—Acid a. Fr., arséniate acide.
