Detailed explanation-1: -In the process of electroplating of silver, the object to be plated (a spoon) is made from the cathode of an electrolytic cell, and a silver bar used as an anode.
Detailed explanation-2: -Silver plate acts as cathode. Was this answer helpful?
Detailed explanation-3: -The electroplating process uses an anode and a cathode. In electroplating, the metal dissolved from the anode can be plated onto the cathode. The anode is provided with direct current, oxidizing and dissolving its metal atoms in the electrolyte solution.
Detailed explanation-4: -The anode is bar of silver metal and the electrodyte must contain Ag+ ions (i.e. AgNO3), so that when the direct current is passed through the cell, positive (Ag+) ions move towards the negative anode (spoon) where they are neutralized by e− and stick to spoon as silver metal.
