In the process of electroplating of copper on a metallic spoon, the iron spoon is made the cathode. When electricity is passed through the solution, Cu2+ ions move towards the cathode and get reduced to copper metal. This copper metal gets electroplated on the object, i.e., the metalic spoon. In silver plating, the object to be plated (e.g., a spoon) is made from the cathode of an electrolytic cell. The anode is a bar of silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of silver cyanide, AgCN, in water.
