A. external electric circuit
B. salt bridge
C. movement of ions
D. all of the above
¨ In an electrolytic cell, an external source of electrical energy is used to drive a non-spontaneous chemical reaction. The direction of electron flow is opposite to that of a galvanic cell.
¨ In an electrolytic cell, the electrons flow from the external power supply to the cathode (where reduction occurs) and away from the anode (where oxidation occurs). This flow of electrons drives the non-spontaneous reaction.
¨ So, in an electrolytic cell, electrons flow from the external power supply to the cathode, which is the opposite direction to that in a galvanic cell.
