Philoid · Accepted Answer

We take a pure copper plate and connect it to the negative terminal of the battery. Therefore, plate A is pure copper plate and is used as cathode.

Now, we take another copper plate which is impure and need to be made pure and is connected to positive terminal of the battery. Therefore, plate B is impure copper plate and is used as anode.

Process:

In the process of electroplating, the copper sulphate solution is used. The copper from impure plate is transferred to pure plate and the impurities get settled below the anode. In this way the impure copper plate becomes purified.
