In the process of silver-plating a metal M, the metal M is the?
anode and a direct current is used
cathode and an alternating current is used
anode and an alternating current is used
cathode and a direct current is used
Correct answer is D
Plating requires ions to flow through an electrolyte in an electric field. Positive ions flow with the electric field, negative ions against the electric field. This electric field comes from a DC supply connected to the electrodes. While silver plating, Ag is the anode while the metal to be coated is the cathode.
