Identification
Name:Arsenate
DescriptionArsenate is a member of the chemical class known as Miscellaneous Arsenites. These are inorganic compounds in which the largest metallic oxoanion is arsenite, to which either no atom or a non metal atom is bonded. The arsenate ion is AsO43-. An arsenate (compound) is any compound that contains this ion. Arsenates are salts or esters of arsenic acid. The arsenic atom in arsenate has a valency of 5 and is also known as pentavalent arsenic or As[V]. Arsenate resembles phosphate in many respects, since arsenic and phosphorus occur in the same group (column) of the periodic table. Arsenates are moderate oxidizers, with an electrode potential of +0.56 for reduction to arsenites. (WikiPedia)
