Arsenate is an ion consisting of arsenic. An arsenate is any compound containing the arsenate ion AsO43−. Arsenates are also referred to as pentavalent arsenic [As(V)] as the arsenic atom in arsenate has a valence of five. Arsenates can be both salts and esters of arsenic acid. Arsenate can be used as an indicator of mineral deposits, as a result of transition metals reacting with it to form bright colours. These mineral blooms can be used to find nickel (annabergite), copper (chalcophyllite), and cobalt (erythrite) arsenide ores. Arsenate is a chemical analogue of phosphate due to arsenic and phosphorous being part of the same group (pnictogens). Because of the similarities, arsenate can be taken by phosphate transporters due to imperfect selectivity (PMID: 328484, 8598055). Arsenate is much less toxic than the trivalent form arsenite, which is more mobile in groundwater and soils, and forms strong metal-like interactions with thiol groups in protein cysteine residues and small molecule thiols (PMID: 30852446). The arsenate ion is AsO43−. An arsenate (compound) is any compound that contains this ion.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.
