For the purification, impure copper is made the:
Correct answer: B. Anode
- A. Cathode
- B. Anode
- C. Solution
- D. Both Cathode and Anode
Explanation
Copper is purified by electrolysis . Electricity is passed through solutions containing copper compounds, such as copper sulfate. The anode (positive electrode ) is made from impure copper and the cathode (negative electrode) is made from pure copper.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
