Arsenic is a chemical element with the symbol As and the atomic number 33. It is a metalloid and one of the pnictogens, and therefore shares many properties with its group 15 neighbors phosphorus and antimony. Arsenic is a notoriously toxic heavy metal.

ARSENIC ACID, LIQUID may evolve very toxic gaseous arsine (AsH3) from contact with active metals, such as zinc and aluminum [Inorganic Chemicals Handbook, I, p. 175]. When heated to decomposition, it produces toxic fumes of metallic arsenic [Sax, 9th ed., p. 271].

2022年12月7日 · The most important action in affected communities is the prevention of further exposure to arsenic by the provision of a safe water supply for drinking, food preparation and irrigation of food crops. There are a number of options …

2009年2月22日 · Arsenic acid, liquid appears as a clear colorless aqueous solution. Noncombustible. Corrosive to metals. Toxic by ingestion. Confirmed human carcinogen. Detrimental to the environment. Immediate steps should be taken to limit release.

Arsenic acid, liquid. Arsenic acid or arsoric acid is the chemical compound with the formula H3AsO4. More descriptively written as AsO(OH)3, this colorless acid is the arsenic analogue of phosphoric acid. Arsenate and phosphate salts behave very similarly.

Liquids containing arsenic. Toxic by ingestion. Obtain the technical name of the material from shipping paper and contact CHEMTREC, 800-424-9300 for specific response information.

Arsenic appears in Group 15 (V) of the periodic table, below nitrogen and phosphorus. Arsenic is. frequently referred to as a metal. Elemental arsenic, which is also referred to as metallic arsenic, (As(0)) normally occurs as the α-crystalline metallic form, which is a steel gray and brittle solid. The β-form is a. dark gray amorphous solid.

2023年9月19日 · A scientific review of two randomized clinical trials found that folic acid supplements may reduce blood arsenic levels and make it easier to get rid of arsenic through the urine in individuals chronically exposed to arsenic-contaminated drinking water.

People are most likely to be exposed to inorganic arsenic through drinking water and to a lesser extent through various foods. Water sources in some parts of the United States have higher naturally occurring levels of inorganic arsenic than other areas.

2025年1月21日 · Arsenic, a metalloid, exhibits a range of chemical properties due to its position in the periodic table. Reaction with Oxygen: Arsenic combines with oxygen to form arsenic oxide (As₂O₃) when heated. The reaction can be represented as: 4As+3O₂ →2As₂ O₃ Arsenic oxide is a white solid and is toxic.
