Transcribed Image Text:

The amount of iron in a meteorite was determined by redox titration using KMnO4 as the titrant. A 0.4185 g sample of the meteorite was dissolved in acid and the liberated Fe³+ was quantitatively converted to Fe²+ using a reducing column. Titrating this solution with 0.02500 M KMnO4 requires 41.27 mL to reach the end-point. Determine the wt% of Fe₂O3 in the sample.
