Which of the following is/are correct processes that take place at cathode and anode during electroplating?
Gain of mass:- Cathode
Reduction of mass:- Anode
The process in which a coherent layer of metal is deposited onto the surface of another metal on passing electricity is known as electroplating or electrodeposition.
Cathode:- The electrode which is connected to the negative terminal of the battery.
Anode:- The electrode which is connected to the positive terminal of the battery.
During electroplating, a coherent layer of metal deposits over the cathode, i.e., the gain of mass. The anode material is similar to the material that needs to be deposited over the cathode and there is a reduction of mass on the anode.
