Introduction of cuprous oxide
Cuprous oxide is a monovalent copper oxide, a bright red powdery solid, almost insoluble in water, disproportionated into divalent copper and copper in an acidic solution, and gradually oxidized into black copper oxide in humid air. Cuprous oxide is mainly used in the manufacture of ship bottom antifouling paints (used to kill low-grade marine animals), insecticides, and various copper salts, analytical reagents, red glass, and also for the preparation of copper plating and copper plating alloy solutions.
