Which of the following types of cells is used for electroplating?

Electroplating is a process that uses electrical energy to drive a non-spontaneous chemical reaction, specifically the deposition of a layer of metal onto a surface.

This process takes place in an electrolytic cell, where an external source of direct current is applied to cause the oxidation and reduction reactions at the electrodes.

Mercury batteries, Leclanche' cells, and fuel cells are galvanic (or voltaic) cells, which generate electrical energy from spontaneous chemical reactions.

Answer: Electrolytic cell
