Which statement is correct?

Question

Quizplus · Accepted Answer

Voltaic cells and electrolytic cells are both types of electrochemical cells, but they operate in opposite ways. In voltaic cells, spontaneous redox reactions generate electrical energy, while in electrolytic cells, electrical energy is used to drive non-spontaneous redox reactions. Therefore, not all electrolytic cells are voltaic cells, and vice versa. Also, corroding metals may involve oxidation or reduction reactions but not necessarily involve an electrolytic process, so statement C is false. Finally, not all electrochemical cells are electrolytic cells, since electrochemical cells can also refer to devices such as biosensors or fuel cells that do not involve the electrolysis of an electrolyte.
