Basic copper carbonate, also known as copper carbonate, is malachite green, so it is also called malachite. It 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 known as copper rust and its color is green. Heating in air will decompose into copper oxide, water and carbon dioxide. Dissolve in acid and form corresponding copper salt. It also dissolves in cyanide, ammonium salt and alkali metal carbonate aqueous solution to form copper complex. When boiled in water or heated in strong alkali solution, brown copper oxide can be formed and decomposed into black copper oxide at 200 ℃. It is unstable in hydrogen sulfide atmosphere and can react with hydrogen sulfide to form copper sulfide. There are more than ten forms of compounds in basic copper carbonate according to the ratio of cuco3: H2O. It exists in the form of malachite in nature.

If it is placed in the air for a long time, it will absorb moisture and release carbon dioxide, and slowly turn into green malachite. It exists in the form of azurite in nature. Copper carbonate and copper bicarbonate do not actually exist. Basic copper carbonate precipitation can be obtained by adding sodium carbonate to dilute copper sulfate solution or passing carbon dioxide into copper hydroxide suspension. Basic copper carbonate can be regarded as composed of copper hydroxide and copper carbonate. In fact, there are two kinds of copper carbonate: one copper hydroxide and two copper carbonate.
The chemical formula of the former 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 turns dark green in the solution after placement. It is toxic and is the main component of green rust (commonly known as copper green) formed on the surface of copper.

The chemical formula of the latter is 2cuco3 · 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 form blue, which decomposes at 300 ℃. Basic copper carbonate can be used to make signal bombs, fireworks, paint pigments, other copper salts, solid phosphor activators, insecticides, seed treatment, bactericides and antidotes, as well as electroplating.

Symptoms of systemic copper poisoning may include: capillary damage, headache, cold sweat, weak pulse, and kidney and liver damage, central nervous system excitation followed by depression, jaundice, convulsions, paralysis, and coma. Death may occur from shock or renal failure. Chronic copper poisoning is typified by hepatic cirrhosis, brain damage and
demyelination, kidney defects, and copper deposition in the cornea as exemplified by humans with Wilson’s disease. It has also been reported that copper poisoning has lead to hemolytic anemia and accelerates arteriosclerosis. To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated.
