In a galvanic (voltaic) cell:
A.Oxidation occurs at the cathode
B.Reduction occurs at the anode
C.Electrons flow from the anode to the cathode
D.The cell potential is always negative
Explanation
Core Concept
In a galvanic cell, oxidation occurs at the anode (producing electrons) and reduction occurs at the cathode (consuming electrons). Electrons flow from anode to cathode through the external circuit.
Correct Answer
CElectrons flow from the anode to the cathode
