Question

Which procedure requires the use of an external electric current to force a redox reaction to occur? a)Polymerization b)Distillation c)Electrolysis d)Saponification

Answer 1

Correct option is c) Electrolysis Explanation:-
Electrolytic cell requires an external current to make a redox reaction spontaneous.
Electrolytic cell is an electrochemical cell in which a nonspontaneous reaction is forced to occur by passing a direct current from an external source into the solution. Thus electrical energy is converted into chemical energy. The cells used for the decomposition of water into hydrogen and oxygen, for the purification of metals, for metal plating are the electrolytic cells.
Electrolysis is the forcing of a nonspontaneous redox reaction to occur by the introduction of electricity into a cell from an outside source.
