Question

Quizplus · Accepted Answer

An electrolytic cell is a cell in which an electric current drives a nonspontaneous reaction. It is the opposite of a galvanic cell or voltaic cell, which is a cell in which the cell reaction is spontaneous. In an electrolytic cell, an external source of electricity is needed to drive the reaction, and the reactants are not present initially, but are added continuously during the reaction.
