It has a molar mass of 229.8402 g/mol. A. Libavius called the same product ‘butyrum arsenici’ (butter of arsenic), although this term was actually used for arsenic trichloride. [6] The water in the alkalies evaporated at 180˚C, and the arsenic pentoxide was stable below 400˚C . [3] The structure differs from that of the corresponding phosphorus(V) oxide; as a result, although there is still a solid solution with that oxide, it only progresses to the equimolar point, at which point phosphorus has substituted for arsenic in all of its tetrahedral sites. The chemical formula is BiF3. Molecular Formula: As 2 H 2 O 6: Synonyms: Arsenic(V) oxide hydrate. Contents. RTECS # CG2275000 CAS # 1303-28-2 ... Molecular Weight. [4], Paracelsus Macquer found a crystallizable salt which he called ‘sel neutre arsenical’.

The table shows element percentages for As 2 O 5 (diarsenic pentoxide). Sometimes called Swarts' reagent, is one of two principal fluorides of antimony, the other being SbF5. More common, and far more important commercially, is arsenic(III) oxide (As2O3). It appears as a white solid. Like all arsenic compounds, the pentoxide is highly toxic. It is used in doping of semiconductors and in the production of explosives and fireworks. [8], Except where otherwise noted, data are given for materials in their, Emergency Planning and Community Right-to-Know Act, National Institute for Occupational Safety and Health, "Comprehensive Treatise on Inorganic & Theoretical Chemistry", Ullmann's Encyclopedia of Industrial Chemistry, "40 C.F.R. Previously Paracelsus heated a mixture of arsenic trioxide and potassium nitrate. Aldrich - 483257; Arsenic(V) oxide 99%; CAS No. 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 is the inorganic compound with the formula As2O5. Likewise, arsenic pentoxide can also dissolve up to an equimolar amount of antimony pentoxide, as antimony substitutes for arsenic only in its octahedral sites. Arsenic pentoxide is the inorganic compound with the formula As2O5. Its reduced derivative arsenite, which is an As(III) compound, is even more toxic since it has a high affinity for thiol groups of cysteine residues in proteins. Arsenic is a chemical element that has the symbol As and atomic number 33. The products that Paracelsus and Libavius found were all impure alkali arsenates. As 2 O 5. More common, and far more important commercially, is arsenic(III) oxide (As2O3). Emergency Planning and Community Right-to-Know Act (42 U.S.C. It contains antimony in the +5 oxidation state.

Arsenic pentoxide. ); This page was last edited on 5 December 2020, at 11:37. Arsenic pentoxide can be synthesized either by burning elemental arsenic in surplus of oxygen, or by oxidizing arsenic trioxide with oxidizing agents such as ozone, hydrogen peroxide and nitric acid. density of arsenic pentoxide is equal to 4 320 kg/m³.In Imperial or US customary measurement system, the density is equal to 269.689 pound per cubic foot [lb/ft³], or 2.5 ounce per cubic inch [oz/inch³] . Oxide compounds are not conductive to electricity. One of the arsenates that he prepared, was arsenic pentoxide. Its usage with respect to arsenic chemistry, as well as its toxicology are similar to arsenic trioxide, As2O3. Geometry of arsenic: Prototypical structure: Element analysis. (3) Arsenic combined with elements such as oxygen, chlorine, and sulfur forms inorganic arsenic; inorganic arsenic compounds include arsenic pentoxide, arsenic trioxide, and arsenic acid.
