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.

33 As Arsenic Description: Arsenic's name comes from the Greek term for an arsenic compound, orpiment (arsenic trisulfide). Arsenic is a metalloid element, which, like phosphorus, has two main forms. One is a brittle, gray metallic form and the other is a yellow, non-metallic solid.Yellow arsenic is the more reactive and unstable of the pair. Arsenic is stable, being unaffected by air, water, most acids and alkalis.Arsenic has no liquid phase; the solid sublimes directly into a vapor.rsenic has semiconductor properties and is used in making transistors. It is also used in alloys, glass production, pyrotechnics and wood preservatives. An arsenic-gallium compound is used in making lasers.

- Arsenic has many applications: Some compounds of arsenic are used as insecticides.In medicine, arsenic trioxide is used in the treatment of psoriasis. An isotope of arsenic (A … s-74) is used as a tracer in some diagnostic imaging.Most metallic arsenic is used in forming alloys of lead and copper. (Unalloyed lead is too soft for many purposes).Arsenic atoms are used to create n-type regions in silicon, when fabricating transistors and integrated circuits.

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.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.

Arsenic in Sea Salt or Concentrace Drops ?? It is probable that we actually need trace amounts of arsenic, as has been demonstrated in the case of some animal studies. We have yet to see a potential depletion in humans, because arsenic is quite ubiquitous in food. Arsenic is also readily excreted, so the main worry is taking in too much in a short time.

- Arsenic trioxide is also important as a raw material for products containing arsenic. Because arsenic is an element like carbon and oxygen it does not break down in the environment into simpler substances-though it can change form and combine with other elements into molecules that have different chemical properties.Some forms of arsenic are quite toxic; others are less so.Most arsenic compounds are undetectable to the senses, since they have no smell or taste. But when arsenic is heated-by bright sunlight or in a laboratory experiment-it passes directly from its solid state to a gas and gives off a distinctive garlic odor.ost arsenic compounds are undetectable to the senses, since they have no smell or taste.

Arsenic Arsenic. Arsenic is a naturally occurring element found in soil and bedrock throughout Wisconsin. Under certain conditions, arsenic can be released into groundwater and enter water wells. Long-term exposure to arsenic in drinking water is known to increase risks of skin, bladder, lung, liver, colon, and kidney cancer.or private residential wells, there is no state or federal requirement that you stop using your water, regardless of the arsenic level. However, if your arsenic level is more than 10 ppb, the Wisconsin Department of Health Services (DHS) recommends that you stop using your water for drinking or food preparation.
