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.

- Drinking water is an important and potentially controllable source of arsenic exposure. In fact, drinking water is a major source of arsenic exposure in some parts of the world. In parts of Taiwan, Japan, Bangladesh, and western South America, high levels of arsenic occur naturally in drinking water.

Arsenic: compounds information The term hydride is used in a generic sense to indicate compounds of the type M x H y and not necessarily to indicate that any compounds listed behave chemically as hydrides. In compounds of arsenic (where known), the most common oxidation numbers of arsenic are: 5, 3, and -3.or each compound, a formal oxidation number for arsenic is given, but the usefulness of this number is limited for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only.

Arsenic contamination of groundwater Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tubewells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people.

Arsenic contamination of groundwater Arsenic contamination of ground water is found in many countries throughout the world, including the USA. Approximately 20 major incidents of groundwater arsenic contamination have been reported.Of these, four major incidents occurred in Asia, in Thailand, Taiwan, and Mainland China.Note that arsenic oxide, As 2 O 3, is a common form of arsenic in groundwater that is soluble, but has no net charge.) Some utilities presently use one of these methods to reduce total dissolved solids and therefore improve taste.

--Chapt. Arsenic poisoning or arsenicosis is a condition caused by the ingestion, absorption or inhalation of dangerous levels of arsenic. Arsenic is a natural semi-metallic chemical that is found all over the world in groundwater. In some areas of the world, natural levels of arsenic in the water are extremely dangerous and hard to detect; arsenic typically has no flavor or odor.

- Formerly the most important use of arsenic compounds, was as an insecticide sprayed in fields and orchards. This use has entirely disappeared in most countries, due to the poisonous nature of arsenic compounds.Arsenic contamination is a problem in some well-water and may be associated with mine drainage.ype: element. Description: Arsenic (As) is classed as a semi-metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur.

What is Arsenic? Arsenic acid and arsenious acid are the forms that are normally found in water – though they may lose some of their H+ atoms depending on the pH. 1  pH is the scale that measures how acidic a solution is. 2  Solutions with a low pH (less than 7, which is neutral) are acidic. 3  Solutions with a high pH are basic.

- Arsenic has a particular affinity for sulfur and is often found joined to sulfur in ores-mixtures of minerals that are mined for profitable materials such as silver or copper. The common ore arsenopyrite, a rusty red rock, is a combination of arsenic with sulfur and iron.ome 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.

- 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 Arsine, AsH 3, is a very poisonous gas with a garlic-like odor. Arsenic metal is very toxic, as are many of its compounds. Cupric hydrogen arsenate and a cupric arsenic-acetate (called Paris green) are used as insecticides.

Metal toxicity Arsenic poisoning is a medical condition caused by elevated levels of arsenic in the body. The dominant basis of arsenic poisoning is from ground water that naturally contains high concentrations of arsenic.A 2007 study found that over 137 million people in more than 70 countries are probably affected by arsenic poisoning from drinking water.hronic arsenic poisoning results from drinking contaminated well water over a long period of time. Many aquifers contain high concentration of arsenic salts.

Arsenic Poisoning 1 Symptoms of arsenic poisoning vary with the type and concentration of the poison. 2  Inorganic arsenic may cause abdominal pains, destruction of red blood cells (hemolysis), shock, and death quickly. Chronic poisoning has a better outcome. 2  Arsenic is found in groundwater, many chemicals, and foods. 3  If arsenic is in the organic form, it is likely nontoxic or weakly toxic to humans, but inorganic arsenic can also be found in similar locations and materials and in high concentrations in industrial processes.

ARSENIC Arsenic is a metalloid. A metalloid is an element that has properties of both metals and non-metals. Metalloids occur in the periodic table on either side of the staircase line that starts between boron and aluminum. When heated in air, arsenic combines with oxygen to form arsenic oxide (As 2 O 3).
