Copper - oxidation and reduction

  1. Jan 16, 2014 #1
    Why the electrical purification of copper involves both an oxidation and a reduction process.

    You understand that the electrical purification requires both an anode and a cathode. Can you explain where the impure copper goes (anode or cathode) and what reaction is taking place there?

    Yeah I guess it does look like a bit like homework, I'll edit the answer. :eek:

    Posts like this where there's almost no effort on the part of the user to elaborate on any aspect of the question are usually suspect.
