Metal plating is done by passing current through a metal solution. For example, an item can become gold plated by attaching the item to a power source and submerging it into a Au3+Au3+ solution. The item itself serves as the cathode, at which the Au3+Au3+ions are reduced to Au(s)Au(s). A piece of solid gold is used as the anode and is also connected to the power source, thus completing the circuit. What mass of gold is produced when 16.2 A...
