the redox reaction in an electrolytic cell is nonspontaneous. electrical energy is required to induce the electrolysis reaction.an example of an electrolytic cell is shown below in which molten NaCl is electrolyzed to from liguid sodium and chlorine gas.the sodium ions migrate toward similarly chlovine gas this type of cell is used to produce sodium and chorine the chlornie gas can be collected surrounding the cell the sodium metal is less dense than the molthen salt and is removed as it floats to the top osf the reaction container
