Describe how you electroplate an iron spoon with copper.

The electric supply should be disconnected from the mains in case of seepage of water near an electrical point. Why?

In the experiment on plating an iron key with copper, what changes will you observe in the mass of the electrodes (the key and the copper plate) before and after the experiment? Will there be a change in the mass of the electrolyte? Draw the circuit diagram of the setup used to electroplate an iron spoon with copper.
