What is the basis for the industrial process in which impure copper is converted into copper of high purity?

Options

  1. AElectrochemical reduction of Cu2+ ions
  2. BElectrochemical reduction of Cu(s)
  3. CElectrochemical oxidation of Cu2+ ions
  4. DElectrochemical oxidation of Cu(s)

Correct answer

D. Electrochemical oxidation of Cu(s)

Step-by-step solution

The industrial process for converting impure copper into copper of high purity is based on the electrochemical oxidation of Cu(s) at the anode.
