Reactions that may be expected to yield CuCO 3, such as mixing solutions of copper(II) sulfate CuSO 4 and sodium carbonate Na 2CO 3 in ambient conditions, yield instead a basic carbonate and CO 2, due to the great affinity of the Cu ion for the hydroxide anion HO .

2022-7-20 This is a demonstration of thermal decomposition. The heat causes the copper (II) carbonate to break down into copper oxide (which is black) and carbon dioxide.
