Cupric oxide NEW

Copper oxide (CuO) is a black oxide of copper that is slightly absorbent. The relative molecular weight is 79.545, the density is 6.3-6.9 g/cm3, and the melting point is 1326℃. Insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solution, slowly dissolved in ammonia solution. The hot CuO can be reduced to copper by hydrogen, carbon, or carbon monoxide.

Carbon monoxide :CuO + CO → Cu + CO2

Carbon :C + 2CuO → CO2 + 2Cu

Hydrogen: CuO + H2 → Cu + H2O

Appearance and properties: black crystalline powder

Density: 6.315

Boiling point: 1026ºC (decomp)

Melting point: 1326ºC

Refractive index: 2.63

Stability: Stable. Incompatible with reducing agents, hydrogen sulfide, aluminium, alkali metals, finely powdered metals.

Storage conditions: Low temperature, ventilation, dry warehouse, separate from food raw materials

Usage:Determination of carbon in gas analysis. Organic reaction catalyst. Manufacture rayon and other copper compounds. Optical glass luminant. As a color material used in artificial gems, colored glass, ceramic glaze.
