In the electrolytic refining of copper, the impure copper is made from the anode in an electrolyte bath of copper sulfate, CuSO 4, and sulfuric acid H 2 SO 4. The cathode is a sheet of very pure copper. As current is passed through the solution, positive copper ions, Cu 2+, in the solution are attracted to the negative cathode, where they take ...

$begingroup$ If it's a research paper, I'd try to test as many metals and alloys (e.g. bronze, brass) as possible (also think of various stainless steels, maybe some screws or alike will do, just grab what you can get) and check what will happen when the metals are used as anode or cathode. For testing cathode materials, it might a good idea …

Electrolytic refining is a process used to purify metals like copper. It involves using electricity to remove impurities from the metal. In the case of copper, impure copper is dissolved in an electrolyte solution, and when an electric current is applied, pure copper is deposited on the cathode. This process helps create high-quality, pure ...
