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.

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.
