Arsenious oxide, commonly known as white arsenic, is obtained as a by-product from the roasting of the ores of copper, lead, and certain other metals as well as by the roasting of arsenopyrite and arsenic sulfide ores.

Being the main compound of arsenic, the trioxide is the precursor to elemental arsenic, arsenic alloys, and arsenide semiconductors. Bulk arsenic-based compounds sodium arsenite and sodium cacodylate are derived from the trioxide.

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.

Jan 15, 2015 · Arsenic has been used by poisoners for centuries, primarily in the form of white arsenic, or arsenic trioxide, which this graphic focuses on. Arsenic Trioxide has, according to some sources, been used in traditional Chinese medicine for over 5000 years.

Arsenic trioxide, also known as white arsenic, arsenic(III) oxide, arsenious oxide, or 砒霜, is a chemical compound. Its chemical formula is As 2 O 3 . It has arsenic and oxide ions in it.

Arsenic forms colorless, odorless, crystalline oxides As 2 O 3 ("white arsenic") and As 2 O 5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic (V) acid is a weak acid and the salts are called arsenates, [5] the most common arsenic contamination of groundwater, and a problem that affects many people.

A higher-purity called white arsenic is obtained by resubliming the crude As2O3 (99+% pure).
