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 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).

The arsenate minerals, which are salts of arsenic acid, contain arsenate groups (AsO 4) in which four oxygen (O) atoms are arranged at the corners of a tetrahedron about a central arsenic (As) atom.

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.

Jun 12, 2023 · Arsenic (As) is a nearly tasteless odorless toxic metalloid element that is found ubiquitously in the environment. Arsenic comes in four common valence states: As (o), As (III), As (V) and Arsine gas and three common forms: inorganic salt, organic salt, and gaseous form.

Lead arsenate is currently used as a growth regulator on U.S. grapefruit crop. 10,000 pounds of lead arsenate are al annually to control cockroaches, silverfish and crickets.

The meaning of ARSENATE is a salt or ester of an arsenic acid.

May 3, 2024 · Arsenate is a compound containing arsenic in its +5 oxidation state, while arsenite features arsenic in the +3 state, affecting their chemical behavior and toxicity. Arsenate compounds typically exist as anions with the formula AsO4^3-, where the arsenic atom is bonded to four oxygen atoms.

Arsenate-reducing bacteria derive their energy from reducing arsenate (As(+5)) to arsenite (As(+3)) via arsenate reductase enzymes. As(+5) can be directly reduced to As(+3) by dissimilatory arsenate reducing prokaryotes (DARPs), yielding energy to support their growth. [3]

Arsenate refers to a subclass of the phosphate mineral group. It consists of an anionic unit, (AsO4)-3, which is coordinated to transition metal or alkaline earth metal with anions (OH-, Cl-, and F-) for charge balancing.
