Which of the following statements about voltaic and electrolytic cells is correct?

Question

Quizplus · Accepted Answer

In a voltaic cell, the anode undergoes oxidation and loses weight, while the cathode undergoes reduction and gains weight. In an electrolytic cell, the opposite occurs. Oxidation occurs at the anode and reduction at the cathode. The flow of electrons in a voltaic cell is from anode to cathode, while in an electrolytic cell, an external power source forces the electrons to flow from cathode to anode. The free energy change (ΔG) is negative for a voltaic cell, meaning the reaction is spontaneous and releases energy. In an electrolytic cell, an external energy source is needed to drive the non-spontaneous reaction.
