An electrolytic cell is an electro chemical cell that drives a non spontaneous redox reaction through the application of electrical energy. They are often used to decompose chemical compounds in a process called electrolysis - the Greek word lysis means break up. Important examples of electrolysis are decomposition of water into hydrogen and oxygen , bauxite into aluminium and other chemicals. Electroplating is done using an electrolytic cell. An electrolytic cell has 3 component parts : an electrolyte and 2 electrodes (cathode and anode). The electrolyte is usually a solution of water or other solvents in which ions are dissolved. Molten salts such as sodium chloride are also electrolytes. When driven by an external voltage applied to the electrodes , the ions in the electrolyte are attached to an electrode with the opposite charge , where charge transferring (also called faradaic or redox) reactions can take place. Only with an external electric potential (i.e voltage) of correct polarity and sufficient magnitude can an electrolytic cell decompose a normally stable , or inert chemical compound in a solution. The electrical energy provided can produce a Chemical reaction which would not occur spontaneously.
