Redox titrations
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:


Redox titrations titrate 50 0 ml 0 050 m fe 2 vs 0 100 m ce 4
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+:
