Chemistry - Metallurgy Question with Solution | TestHub

In electrolytic refining of copper, impure copper acts as the anode and pure copper as the cathode. During electrolysis, copper from the impure anode oxidizes and dissolves into the electrolyte as Cu²⁺ ions. These ions then migrate to the pure copper cathode, where they gain electrons and deposit as pure copper. Thus, pure metal is transferred from the anode to the cathode.
