Cu+2 + CO 3 -2 Cu. CO 3 * copper (II) carbonate is the green pigment in malachite. Occurs in Egyptian tomb paintings since the fourth dynasty, in European paintings it seems to have been of importance mainly in the 15 th and 16 th centuries. The solution of sodium carbonate is being added to the solution of copper (II) sulfate Gaseous carbon dioxide is being formed Resulting copper (II) carbonate is being filtered off 65
