Bismuth pentoxide is a chemical compound composed of bismuth and oxygen, with the chemical formula Bi2O5.[1] It is a dark red powder decomposing above 100 °C.[citation needed] It is not known as a pure substance, but is usually mixed with water, bismuth tetroxide or bismuth trioxide.[2]
An uncharacterized chocolate-brown or orange powder is produced by boiling salts of bismuthate(V) (e.g. NaBiO3) in nitric acid. The color of the resulting product is dependent on the specific bismuthate used, and it is possibly a mix of residual bismuthate, bismuth pentoxide, and bismuth tetroxide.[3]
