Nomenclature
CAS number: 1303-57-7
Aurous oxide.
Description and references
Existence doubtful; probably a mixture of gold
and auric oxide: Pollard, J. Chem. Soc. 129, 1347 (1926). “Au2O” has been prepared
by treating K(AuBr2) with alkali.
Properties
Pale gray-violet solid. May be dried at 200°,
but gives off oxygen a few degrees above this, and rapidly at 250°.
Soly in water (25°): 0.04 mg/l. When freshly precipitated, it dissolves
in alkalies, but the soln deposits gold rapidly.Status
