Question

A cell from the following which converts electrical energy into chemical energy?
(A) Dry cell
(B) Electrochemical cell
(C) Electrolytic cell
(D) None of these

Answer 1

Hint: Conversion of electrical energy into chemical energy, this process is known as the electrolysis process, in which it involves a simultaneous oxidation reaction at anode and a reduction reaction at the cathode that happens by its cell.

Complete answer:
Electrolytic cell is a type of cell which converts electrical energy into chemical energy.
An electrolytic cell is an electrochemical cell that drives a non-spontaneous redox reaction with electrical energy. Electrolysis—the Greek term lysis means "to break up"—is frequently employed to break down chemical substances. Electrolysis is used to break down water into hydrogen and oxygen, as well as bauxite into aluminium and other compounds. An electrolytic cell is used to electroplate (for example, copper, silver, nickel, or chromium). Electrolysis is a technique that uses a direct electric current (DC).
There are three pieces to an electrolytic cell: an electrolyte and two electrodes (a cathode and an anode). The electrolyte is typically a dissolved ion solution in water or other solvents. Electrolytes include molten salts like sodium chloride. The ions in the electrolyte are attracted to an electrode with the opposite charge when an external voltage is supplied to the electrodes, allowing charge-transferring (also known as faradaic or redox) events to occur. An electrolytic cell can only break down a typically stable or inert chemical substance in solution with an external electrical potential (i.e., voltage) of the correct polarity and adequate magnitude. The electrical energy can cause a chemical reaction that would not happen naturally otherwise.
Hence, the correct option is (C) Electrolytic cell.

Note:
Any device that converts electrical energy to chemical energy or vice versa. Two metallic or electronic conductors (electrodes) are maintained apart from one another and in contact with an electrolyte (q.v.), which is commonly a dissolved or fused ionic compound.
