Cuprous oxide
1. Properties: red or dark red eight-sided cubic crystal system crystalline powder. It quickly turns blue in the air and gradually oxidizes to black copper oxide in wet air.
　　
2. Density (g/mL,25/4 ℃): 6.0
　　
3. Relative vapor density (g/mL, air = 1):4.9
　　
4. the NC (°c):1235
　　
5. Boiling point (°C, atmospheric pressure):1800
　　
6. Refractive index: 2.705
　　
7. Flash point (C): 1800
　　
8. Solubility: insoluble in water and alcohol, soluble in hydrochloric acid, ammonium chloride, ammonia, slightly soluble in nitric acid. Dissolved in hydrochloric acid to generate white cuprous chloride crystalline powder. In case of dilute sulfuric acid and dilute nitric acid, copper salts are generated. It quickly turns blue in the air. Soluble in concentrated alkali, ferric chloride and other solutions.

Basic copper carbonate

Basic copper carbonate, malachite green color, so also called malachite, is a precious mineral gem. It is a substance produced by the reaction of copper with oxygen, carbon dioxide and water vapor in the air, also known as patina, green in color. Heating in air decomposes into copper oxide, water and carbon dioxide. It dissolves in acid and forms the corresponding copper salt. It exists in nature in the form of malachite.
