Question

In a spontaneous redox reaction, electrons flow from:

RankGuru · Accepted Answer

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