When 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. Copper(II) carbonate, also known as cupric carbonate, is a chemical compound. Es ist in Wasser unlöslich und zersetzt sich ab 140 °C zu Kupfer(II)-oxid und Kohlenstoffdioxid: Bei der Reaktion mit Säuren entsteht Kohlenstoffdioxid und das Kupfersalz der Säure: Kupfer(II)-carbonat wird zur Herstellung vieler Kupferverbindungen, wie Kupfersulfat, CuSO4 und Kupfer(II)-oxid, CuO, verwendet. Copper metal when exposed to air turns green in colour due to corrosion. Its chemical formula is CuCO 3.
