We preformed a potentiometric titration of Fe2+ by Ce4+ in lab and needed 9.73 mL of .1 M Ce4+ to reach the equivalence point. Our initial volume of Fe2+ was 10.0 mL and 15.0 mL of deionized water.
The equation is Ce4+ + Fe2+ --> Ce3+ + Fe3+
1. Use this data to calculate the concentration of Fe2+ in your sample.
2. Calculate the potential of the reaction of Ce4+ and Fe2+ under standard conditions.
3. Using the equation, nFE=RTlnK, calculate the equilibrium constant for this reaction.
