Short description: Chemical compound

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]
