Concept #1:

Within a redox titration we can utilize indicators and electrodes to determine the end point.

 

The titration curve for the titration of 50.0 mL of 0.100 M Fe2+ with 0.100 M Ce4+ can be seen below:

Additional Problems
You are titrating a weak acid (pKa = 5.00) with a strong base. Which of the following indicators would likely be best for determining the “end point” as an estimate of the equivalence point? a) Methyl Violet – Transition Range: pH 0.0 – 1.6b) Cresol Red – Transition Range pH 0.2 – 1.8 c) Cresol Purple – Transition Range pH 7.6 – 9.2d) Methyl Orange – Transition Range pH 3.1 – 4.4
