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]

砷酸盐包括正砷酸H3AsO4、偏砷酸HAsO3和焦砷酸H4As2O7的盐类。有正盐、酸式盐和碱式盐。碱金属的砷酸盐溶于水，例如砷酸钠Na3AsO4、砷酸二氢钾KH2AsO4等。其他金属的砷酸盐几乎不溶于水，例如砷酸钙Ca3(AsO4)2、砷酸铅Pb3(AsO4)2、碱式砷酸铅Pb5(OH)(AsO4)3等。砷酸盐有毒，可以用杀虫剂等。

IUPAC have recommended that arsenite compounds are to be named as arsenate(III), for example ortho-arsenite is called trioxidoarsenate(III). Ortho-arsenite contrasts to the corresponding anions of the lighter members of group 15, phosphite which has the structure HPO 2− 3 and nitrite , NO − 2 which is bent.

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 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 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).

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 ...

It is thought that the binding of arsenite to peptide sulfhydryl groups is the main mechanism causing arsenite toxicity. By competing with phosphate, arsenate is known to impair oxidative phosphorylation. Arsenate's toxicity to biota is typically decreased in situations with high phosphate concentrations [61,62]. The highest acceptable ...
