Solution
Correct Answer:
Anode to cathode
- Anode: The electrode where oxidation (loss of electrons) occurs. In a galvanic cell, it is the negative terminal.
- Cathode: The electrode where reduction (gain of electrons) occurs. In a galvanic cell, it is the positive terminal.
- Electron Flow: Electrons are produced at the anode by the oxidation half-reaction and are consumed at the cathode by the reduction half-reaction.
- Circuit: Therefore, electrons travel through the external wire from the Anode to the Cathode.
- Note: Conventional current flows in the opposite direction (Cathode to Anode).
