Answer» Basically in the silver PLATING method, the silver bar as the anode, the object is to be plated acts as the cathode and the double cyanide of POTASSIUM and silver acts as the electrolyte. When the direct ELECTRIC current is PASSED between the anode and the cathode, the POSITIVE silver ions (Ag + ) from the double cyanide of silver and potassium solution to the negative anode (the object), where they are neutralized by the electrons and stick to the object as silver metal.
