Arsenic pentoxide is the inorganic compound with the formula As 2 O 5. [2] . This glassy, white, deliquescent solid is relatively unstable, consistent with the rarity of the As (V) oxidation state. More common, and far more important commercially, is arsenic (III) oxide (As 2 O 3).

2009年2月22日 · Arsenic pentoxide is a commerical oxide of arsenic frequently used in the production of other arsenic compounds. It dissolves readily in water to form arsenic acid and decomposes into oxygen and arsenic trioxide when heated.

ARSENIC PENTOXIDE. Oxidation of elemental arsenic or arsenic trioxide by nitric acid, followed by evaporation of the resulting mixture and dehydration of the residue, yields white hygroscopic crystals of arsenic pentoxide. Thermal decomposition of the pentoxide converts it to the trioxide with concurrent loss of oxygen.

Arsenic pentoxide is used as a solid or as a solution in the manufacturing of arsenates, weed killer, metal adhesives, insecticides, fungicides, wood preservatives, and colored gases and in printing and dyeing.

Arsenic pentoxide, also known as arsenic (V) oxide, is a chemical compound. Its chemical formula is As 2 O 5. It has arsenic and oxide ions in it. The arsenic is in its +5 oxidation state. More common is arsen in its oxidation state +3 as As 2 O 3 (arsenic trioxide or arsenic (III) oxide). The LD50 for arsenic pentoxide is 8mg/kg for rats. [1] .

ARSENIC PENTOXIDE is an oxidizing acid. Oxidizing acids are generally soluble in water with the release of hydrogen ions. The resulting solutions have pH's of less than 7.0. Materials in this group react with chemical bases (for example: amines and inorganic hydroxides) to form salts.

Of the inorganic arsenic compounds, arsenic trioxide, sodium arsenite and arsenic trichloride are the most common trivalent compounds, and arsenic pentoxide, arsenic acid and arsenates (e.g. lead arsenate and calcium arsenate) are the most common pentavalent compounds.
