What is ARSENIC(V) OXIDE HYDRATE?
Chemical properties
white powder
Chemical properties
Arsenic pentoxide is an odorless white lumpy solid or powder and nonflammable. It may be shipped as a concentrated water solution.
Potential Exposure
Arsenic pentoxide is used in production of metal arsenates; as an herbicide, defoliant on cotton; as a chemical intermediate; as an ingredient in wood preservatives; and in glass. Other possible uses are as an insecticide and soil sterilant.
Shipping
UN1559 Arsenic pentoxide, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Decomposes above 315 C, forming oxygen and arsenic trioxide fumes. Arsenic pentoxide is an oxidizer; reacts violently with bromine pentafluoride and reducing agents. The solution in water is a weak acid. Incompatible with acids, strong alkalis; halogens, rubidium carbide, zinc. Corrosive to metals in the presence of moisture. Contact with acids or acid mists releases deadly arsine gas.
Waste Disposal
Dissolve in a minimum of concentrated hydrochloric acid. Dilute with water until white precipitate forms. Add HCl to dissolve. Saturate with H2S; filter and wash precipitate and return to supplier. Alternatively, precipitate with heavy metals, such as lime or ferric hydroxide in lieu of H2S. If needed, seek professional environmental engineering assistance from the United States Environmental Protection Agency Environmental Response Team at (908) 548-8730 (24-hour response line). Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/ mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
