WebWhen copper vessel is exposed to air in rainy season, the metal reacts with gases, moisture and atmospheric gases to form a mixture of copper carbonate and copper hydroxide. This gives a green colour to the surface of copper metal. The reaction is as follows: 2Cu+H 2O+CO 2+O 2→Cu(OH) 2+CuCO 3. Hence, copper becomes green when exposed to moist … WebCopper + Oxygen → Copper oxide 2Cu (s) + O 2 (g) → 2CuO (s) This experiment could be used as an illustration of the likely reactions of other transition metals with oxygen, as they all have similar properties. It could also provide a contrast to the reactions of Group 1 and 2 metals with oxygen. Additional information
