Detailed Solution

The above statement is False.
Electroplating is the process of depositing a layer of one metal on another using electrolysis. The cathode is the object to be coated, and the anode is the metal to be deposited. Less expensive metals are electroplated with more expensive metals to protect them from corrosion and scratches. Silver and gold are electroplated on less expensive metals by jewellers.
The correct statement would be that objects made from less expensive metals are electroplated with expensive metals to look more attractive.
