Answer options

  1. Cathode
  2. Anode
  3. Vessel
  4. Electrolyte

Correct answer and explanation

Correct answer: Cathode

Explanation: āœ… Correct Answer: A) Cathode šŸ“š Explanation: During the industrial process of electrolytic refining, the pure metal ions present in the solution gain electrons and are reduced, causing them to deposit onto the negative electrode, which is the 'Cathode'. The thick, impure block of metal acts as the positive 'Anode' and continuously dissolves into the electrolyte. This method is widely used to obtain copper and gold at extremely high purities.
