In an electrolytic cell, compared to a galvanic cell:
A.Oxidation occurs at the cathode
B.The cell potential is always positive
C.No external power source is needed
D.The anode is positive and the cathode is negative
Explanation
Core Concept
In an electrolytic cell (which requires external power), the anode is positive and cathode is negative—the opposite of a galvanic cell. The external power source forces the non-spontaneous reaction to occur.
Correct Answer
DThe anode is positive and the cathode is negative
