The concentration of a Fe2+ solution
is determined by titrating it with a 0.1462 M
solution of Ce4+. The balanced net
ionic equation for the reaction is shown below.
Ce4+(aq)
+ Fe2+(aq)
Ce3+(aq)
+ Fe3+(aq)
In one experiment, 16.48 mL of the
0.1462 M Ce4+ solution
is required to react completely with 25.00 mL of
the Fe2+ solution. Calculate the
concentration of the Fe2+ solution.

In a potentiometric titration of iron with cerium, the reaction is Fe2+ + Ce4+ --> Ce3+ + Fe3+. After collecting data it was found that 0.8925 grams of iron could be titrated with 20.95 milliliters of 0.04945 Molarity cerium(IV) to reach an end point with a potential of 0.806 Volts. Using the Nernst equation [Ecell = {E^o (Fe) - 0.0592 log {(21.05 - Volume added)/Volume added}} - Eref], calculate values of formal electrode potentials for reduction of iron...

A
0.1362g iron ore sample was dissolved in hydrochloric acid and the
iron was obtained as Fe^2+(aq). The iron solution was titrated with
Ce4+ solution according to the balanced chemical reaction shown
below. After calculation, it was found that 0.0238g of iron from
the ore reacted with the cerium solution.
Ce^4+(aq) + Fe 2+(aq) -> Ce^3+(aq) + Fe^3+(aq).
Calculate the mass percent of iron in the original ore sample.
