Chemistry - Redox Reactions - Standard electrode potentials - Using the E° Table
3 worked examples using standard electrode potentials. Example 1: 'Calculate E°cell for Zn-Cu cell.' Work: 'Cathode (reduction): Cu²⁺ + 2e⁻ → Cu, E° = +0.34V. Anode (oxidation): Zn → Zn²⁺ + 2e⁻, E° = -0.76V. E°cell = E°cathode - E°anode = +0.34 - (-0.76) = +1.10V. Positive → spontaneous!' Example 2:
