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.

Copper sulfate (copper sulfate), inorganic compounds, chemical formula CuSO4. White or off-white powder. The aqueous solution is weakly acidic and blue. However, when crystallized from aqueous solution, blue copper sulfate pentahydrate (CuSO4 · 5H2O, also known as chalcanthite) is generated. This principle can be used to test the presence of water. Heat after the loss of crystal water decomposition, at room temperature and pressure is very stable, not deliquescence, in dry air will gradually weathering.

Copper carbonate is precipitated copper carbonate is a carbonate of copper, blue-green powder solid.
Copper carbonate is a carbonate of copper and is a blue-green powdery solid. There is no copper carbonate in the aqueous solution, and copper carbonate is immediately bihydrolyzed to a mixture of copper hydroxide and basic copper carbonate (the specific product depends on the acidity and alkalinity of the solution).
