What is electroplating?

• It is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur.

• It is an electrochemical process in which current is passed between two electrodes through an ionized solution

• It is the process of the process of aligning another metal onto a metal.

It refers to a device converting chemical energy into

electrical energy using a combustion reaction.

• Cathode

• Electrolyte

• Electrolytic cell

• Fuel Cell

It is a type of chemical reaction that involves a transfer of electrons between two species.
