The stability of dry CuCO 3 depends critically on the partial pressure of carbon dioxide (pCO2). It is stable for months in dry air, but decomposes slowly into CuO and CO 2 if pCO2 is less than 0.11 atm. In the presence of water or moist air at 25 °C, CuCO 3 is stable only for pCO2 above 4.57 atmospheres and pH between … See more Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO 3.
