Usage And Synthesis
Malachite

Cupric carbonate basic exhibits the color of malachite green, thus being called malachite, being a precious mineral gem. It is product produced from the reaction between copper and the oxygen, carbon dioxide and water in the air, also known as copper rust with green color. When being heated in the air, it will be broken down into copper oxide, water and carbon dioxide. It is soluble in acid and can generate the corresponding copper salt. It is also soluble in the aqueous solution of cyanide, ammonium salt and alkali metal carbonate to form copper complex. When being boiled in water or heated in alkaline solution, it can generate brown copper oxide. At 200 ºC, it can be decomposed into black copper oxide. It is very unstable under hydrogen sulfide atmosphere and can have reaction with hydrogen sulfide to generate copper sulfide. Cupric carbonate basic, according to the ratio difference of CuCO3 over H2O, has a dozen different forms of compounds. It is existed in the form of malachite in nature in the form of malachite.
When being placed in the air for a long time, it will absorb moisture and release carbon dioxide, slowly turning into the green malachite composition. In nature, it is existed in the form of blue copper.
