碱式碳酸铜（Auragreen） Auragreen directory [hide] Chemical property Physical property Chemical description: Preparation and use [edit this paragraph] chemical properties Chemical properties, chemical formula is Cu2 (OH) 2CO3, also known as malachite, is a rare mineral gem. It is the reaction of oxygen, carbon dioxide and water and other substances in the air and copper material, also called patina (P.). Heating in the air will break down into copper oxide, water, and carbon dioxide. Aeruginosa (rust) and aerugo. Copper reacted with O2, CO2, and H2O in air to produce Cu2 (OH) 2CO3. Heating generates CuO, CO2, H2O. Chemical formula: Cu2 (OH) 2CO3 2CuO+CO2 +H2O one one heating up Adding sodium carbonate in dilute copper sulfate solution, or carbon dioxide into the copper hydroxide suspension, can get the basic copper carbonate precipitation. Aerugo can be regarded as consisting of copper hydroxide and copper, a copper hydroxide has two copper and copper two. The former chemical formula is CuCO3 Cu (OH) 2, a green, monoclinic crystalline fibrous mass or dark green powder. By the solution of the precipitate showed green, placed in the solution becomes dark green. It is toxic because it reacts with hydrochloric acid in the stomach to produce copper ions that cause heavy metal poisoning. After poisoning should drink: 1, drink fresh milk or egg white solution 2, sodium sulfate solution 3, sodium bicarbonate solution. Verdigris is generated on the surface of copper patina (commonly known as the main component of P.). It also exists in nature in the form of minerals, commonly known as malachite. It is insoluble in water, soluble in acid, hot water or heating to 220 DEG is decomposed into water and carbon dioxide (copper oxide, copper oxide, copper carbonate heating + water + carbon dioxide). Soluble in acids and yield corresponding copper salts. A complex of copper that is also soluble in cyanide, ammonium salts, and alkali metal carbonate solutions. The latter chemical formula is
