- 1Oxidation takes place at the cathode and reduction takes place at the anode in a galvanic cell.
- 2A negative E° value means the redox couple is a weaker reducing agent than the H+/H2 couple.
- 3A positive E° value means the redox couple is a stronger reducing agent than the H+/H2 couple.
- 4A negative E° value means the redox couple is a stronger reducing agent than the H+/H2 couple.✓
Correct answer
A negative E° value means the redox couple is a stronger reducing agent than the H+/H2 couple.
