3. Draw a diagram showing the electroplating of copper on an iron spoon.
4. Write chemical reactions describing the electroplating of copper.

Answer 1

Ans:1 Electrolyte: Liquid that conduct electricity

         Electrolysis: Circuit made by a conducting liquid

          Electrodes: Metals that are connected to anode and cathode for connectivity.

          Volameter: A device used in measuring the power of the circuit.

Ans :2 Electrolysis can happen in liquids that have ions which is only possible in those molecules that give and take electrons. Acids give and take electrons due to which, when we add acid in  water and turn on the electricity, the energy dissociates it and forms ions which helps in the movement of electricity and forms a complete circuit.
