Copper is a red metal, the ions of this metal in solution give it a blue color. but copper carbonate is green. it means that when copper products are exposed to air for a long time, it is this salt that is formed. This happens when this metal interacts with carbon dioxide in moist air:
2Cu + CO2 + H2O + O2 = CuCO3 + Cu (OH) 2
