Inkompatibilit?ten
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.
