Question

Which of the following is correct for electroplating a metal X with copper through electrolysis?

  1. Copper-cathode
  2. Metal X-anode
  3. Copper sulfate solution as an electrolyte
  4. All the above

hintHint:

Copper sulfate has copper ions which are metals used in electroplating.

The correct answer is: Copper sulfate solution as an electrolyte


    • The electrolyte has ions that carry and conduct the charge.
    • The copper sulfate solution has copper ions that are good conductors.
    • Copper is used to doing electroplating.
