Basic copper carbonate, also known as copper rust, patina, chemical formula Cu2(OH)2CO3, is a substance caused by the reaction of copper with substances such as oxygen, carbon dioxide and water vapor in the air. Heating in the air will decompose into copper oxide, water and carbon dioxide, which dissolve in acid and form the corresponding copper salt
