The preparation methods of cuprous oxide
Cuprous oxide is an oxide of monovalent copper. It is a bright red powder solid, almost insoluble in water. It is disproportionated into monovalent copper and copper in acidic solution, and gradually oxidized into black copper oxide in wet air. Cuprous oxide is mainly used in the manufacture of anti-fouling paint (used to kill low-grade marine animals), pesticides, as well as various copper salts, analytical reagents, red glass.
