How can the exess copper carbonate be removed?

Final answer: Excess copper carbonate is typically removed by adding a reagent like sodium carbonate to precipitate it out of the solution, which can then be filtered out. This process is part of larger industrial procedures that involve several steps to purify copper from its ores. Explanation: To remove excess copper carbonate, a method called precipitation can be utilized. If, for instance, in a solution with copper ions, a reagent that forms an insoluble compound with copper, such as sodium carbonate (Na2CO3), is added, the copper will precipitate out of the solution as copper carbonate. In a test tube experiment, when you add the sodium carbonate solution to a solution containing copper(II) chloride, a visible precipitate of copper carbonate forms which can be removed by filtration. However, when sodium sulphate is added instead, no such precipitation occurs because copper sulphate remains soluble in water. In industrial settings, this concept is scaled up to purify copper from its ore through steps that include roasting to remove volatile impurities, using flux such as limestone to aid in forming separating out impurities, and oxidation-reduction reactions to reduce copper compounds to metallic copper.
