Arsenic The most important compounds of arsenic are arsenic (III) oxide, As 2 O 3, (' white arsenic '), the yellow sulfide orpiment (As 2 S 3) and red realgar (As 4 S 4), Paris Green, calcium arsenate, and lead hydrogen arsenate.The latter three have been used as agricultural insecticides and poisons.he most common oxidation states for arsenic are -3 (arsenides: usually alloy-like intermetallic compounds), +3 (arsenates(III) or arsenites, and most organoarsenic compounds), and +5 (arsenates(V): the most stable inorganic arsenic oxycompounds).

Arsenic The main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in car batteries). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon.rsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however. A few species of bacteria are able to use arsenic compounds as respiratory metabolites.

Questions & Answers: Arsenic in Rice and Rice Products What is arsenic? Arsenic is an element in the Earth’s crust, and is present in water, air, and soil. It occurs both naturally in the environment and as a result of human activity, including from erosion of arsenic-containing rocks, volcanic eruptions, contamination from mining and smelting ores and previous or current use of arsenic-containing pesticides.

Arsenic Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. broad variety of sulfur compounds of arsenic are known. Orpiment (As2S3) and realgar (As4S4) are somewhat abundant and were formerly used as painting pigments. In As 4 S 10, arsenic has a formal oxidation state of +2 in As 4 S 4 which features As-As bonds so that the total covalency of As is still 3.

Arsenic Studies in laboratory animals indicate that administration of trivalent inorganic arsenic such as As2O3 and arsenite initially results in higher levels in most tissues than does the administration of pentavalent arsenic. However, the trivalent form is more extensively methylated, leading to similar long-term excretion.

- The three most common arsenic allotropes are metallic gray, yellow, and black arsenic, with gray being the most common. Gray arsenic (α-As, space group R 3 m No. 166) adopts a double-layered structure consisting of many interlocked, ruffled, six-membered rings.he most common oxidation states for arsenic are: −3 in the arsenides, such as alloy-like intermetallic compounds; and +3 in the arsenites, arsenates(III), and most organoarsenic compounds. Arsenic also bonds readily to itself as seen in the square As 3− 4 ions in the mineral skutterudite.

What is Arsenic? If you add the valences of each atom in the molecular formula for arsenious acid, H 3 AsO 3, you can see that the molecule, which is uncharged, has a total valence state of 0 (3x(+1) for the hydrogen atoms; 1x(+3) for the arsenic(III) atom; 3x(-2) for the oxygen atoms = 3+3-6 = 0).
