Chemistry Form Four: Chapter 6 - Electroplating of copper metal

1) Anode --> plating metal = copper
2) Cathode --> object to be electroplated = iron key

3) Electrolyte --> salt solution that contains electroplating metal ions = copper (II) sulphate

cathode: A brown metal deposited on the surface of the iron key.

anode: Copper anode becomes thinner.

Dear Students,
 You can also watch the electroplating of metal in industry through below video.
