Reference Information
| basic copper carbonate | copper carbonate, also known as basic copper carbonate, is malachite green, so it is also called malachite, which is a precious mineral gem. It is a substance produced by the reaction of copper with oxygen, carbon dioxide and water in the air. It is also called copper rust and is green in color. Heating in air will decompose into copper oxide, water and carbon dioxide. Soluble in acid and form the corresponding copper salt. It is also soluble in cyanide, ammonium salt and alkali metal carbonate aqueous solution to form copper complexes. When boiled in water or heated in a strong alkali solution, brown copper oxide can be generated, which is decomposed into black copper oxide at 200°C. It is unstable in a hydrogen sulfide atmosphere and can react with hydrogen sulfide to form copper sulfide. Basic copper carbonate has more than a dozen forms of compounds according to the ratio of CuCO3:H2O. It exists in the form of malachite in nature. |
| chemical reaction | when placed in the air for a long time, it absorbs moisture and emits carbon dioxide, slowly turning into green malachite composition. It exists in nature in the form of blue copper ore. Copper carbonate and copper bicarbonate actually do not exist. Adding sodium carbonate to dilute copper sulfate solution or passing carbon dioxide into copper hydroxide suspension can obtain basic copper carbonate precipitate. Basic copper carbonate can be regarded as composed of copper hydroxide and copper carbonate. In fact, there are two types of copper hydroxide, one copper carbonate and two copper carbonate. The former chemical formula is CuCO3 · Cu(OH)2, which is a grass-green monoclinic crystalline fibrous mass, or dark green powder. The precipitate obtained from the solution initially appears green, and becomes dark green in the solution after being placed. It is toxic and is the main component of the green rust (commonly known as patina) generated on the surface of copper. The latter chemical formula is 2 CuCO3 · Cu(OH)2, dark sky blue, very bright monoclinic crystals, or compact crystalline clusters. It is insoluble in water, soluble in ammonia and hot and concentrated sodium bicarbonate solution to become blue, and decomposes at 300°C. |
| use | basic copper carbonate can be used to make flares, fireworks, paint pigments, other copper salts, solid phosphor activators, pesticides, seed treatment, fungicides and antidotes, as well as electroplating, etc. |
