Reaction of copper with moist air
WebJun 22, 2024 · Copper oxide then combines with carbon dioxide to make copper carbonate, which gives it a green colour. This process is called corrosion of copper. The green material is a mixture of copper hydroxide (Cu(OH) 2) and copper carbonate (CuCO 3). The following is the reaction 2Cu + H 2 O + CO 2 + O 2 → Cu (OH) 2 + CuCO 3 moist air. WebWhen a copper vessel is exposed to moist air firstly the copper vessel will turn to green color because of the reactivation of the copper with the moist air that is the hydrogen and the oxygen and even some other molecules or compounds.
