  1. Redox Titrimetry and Potentiometry

  2. Redox Titrations • Titrate 50.0mL of 0.050 M Fe2+ vs 0.100M Ce4+ • How do we observe the end point? • Is the equilibrium constant large enough? • To Observe End Point:

  3. Redox TitrationsTitrate 50.0 mL 0.050 M Fe2+ vs 0.100 M Ce4+ • Use Pt Indicator Electrode: • Ept= EFe3+/Fe2+ = ECe4+/Ce3+ at Equilibrium • a) Add 10.0 mL Ce4+:

  4. Redox TitrationsTitrate 50.0 mL 0.050 M Fe2+ vs 0.100 M Ce4+ • b) At 50% of Titration (12.50 mL Ce4+)

  5. Redox TitrationsTitrate 50.0 mL 0.050 M Fe2+ vs 0.100 M Ce4+ • c) Just Before Equivalence Point (24.90 mL Ce4+)

  6. Redox TitrationsTitrate 50.0 mL 0.050 M Fe2+ vs 0.100 M Ce4+ • d) Just Beyond Equivalence Point (25.10 mL Ce4+)

  7. Redox TitrationsTitrate 50.0 mL 0.050 M Fe2+ vs 0.100 M Ce4+ • e) Equivalence Point Potential (25.00 mL Ce4+)

  8. Redox TitrationsTitrate 50.0 mL 0.050 M Fe2+ vs 0.100 M Ce4+ • e) Equivalence Point Potential (25.00 mL Ce4+)

  9. Redox TitrationsTitrate 50.0 mL 0.050 M Fe2+ vs 0.100 M Ce4+
