The arsenate is an ion with the chemical formula AsO 3− 4. [1] Bonding in arsenate consists of a central arsenic atom, with oxidation state +5, double bonded to one oxygen atom and single bonded to a further three oxygen atoms. [2] The four oxygen atoms orient around the arsenic atom in a tetrahedral geometry. [2]

arsenate mineral, any of a group of naturally occurring compounds of arsenic, oxygen, and various metals, most of which are rare, having crystallized under very restricted conditions. At the mineralogically famous Långban iron and manganese mines in central Sweden, more than 50 species of arsenate minerals have been described, many peculiar to ...

Arsenate is an ion. Its chemical formula is AsO 4 3-. It has arsenic in its +5 oxidation state. Arsenates are salts of arsenic acid. They are oxidizing agents. Sometimes, not all of the protons are taken away from the arsenic acid and then hydrogen arsenate salts are formed.

Arsenate minerals usually refer to the naturally occurring orthoarsenates, possessing the (AsO 4) 3− anion group and, more rarely, other arsenates with anions like AsO 3 (OH) 2− (also written HAsO 4 2−) (example: pharmacolite Ca(AsO 3 OH). 2H 2 O) or (very rarely) [AsO 2 (OH) 2] − (example: andyrobertsite).

Arsenate (HAsO 4 −2) can be used as a substitute for inorganic phosphate, but because most phosphate liberating processes are effectively irreversible (e.g. ATP→ADP + Pi), the number of enzymes that use inorganic phosphate as substrate is limited (for example, only about a dozen such enzymes could be identified in the E. coli genome using ...

Arsenates are salts or esters of arsenic acid that contain the arsenate ion (AsO 4 3 −) in its chemical formula. They are considered a subclass of the phosphate mineral group because of the similarity in size and charge of phosphate and arsenate anionic units (Flora, 2015). Trivalent arsenicals, in turn, comprise several compounds, including ...
