what is the method of purification of copper
Answers
Answer:
Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.
Answer:
Explanation:
A rod of pure copper is used as a cathode and the impure copper is an anode. The electrolyte (solution the ions travel through) is a solution of copper (II) sulphate (CUSO4).
During electrolysis, copper (II) ions leave the impure copper anode and since they are positive, they are attracted to the negative cathode. Here they pick up the two electrons that are needed to form a copper metal, and this builds up pure copper. Impurities from the anode collect at the bottom of the solution.
