Problem 102P

A 1.012-g sample of a salt containing Fe2+ is titrated with 0.1201 M KMnO4. The end point of the titration is reached at 22.45 mL. Find the mass percent of Fe2+ in the sample. The unbalanced redox reaction that occurs in acidic solution during the titration is:

Fe2+(aq) + MnO4− (aq) → Fe3+(aq) + Mn2+ (aq)

Step-by-Step Solution:

Solution 102 P:

Here, we are going to calculate the mass percent of Fe2+ in the sample.

Step 1:

The balanced equation for the redox reaction is

5Fe2+(aq) + MnO4 (aq) +8H+(aq) → 5Fe3+(aq) + Mn2+ (aq) + 4H2O(l)
