Question

The iron content of iron ore can be determined by titration with standard KMnO4 solution. The iron ore is dissolved in HCl, and all of the iron is reduced

to Fe2+ ions. This solution is then titrated with KMnO4 solution, producing Fe3+ and Mn2+ ions in acidic solution. What is the mass of KMnO4 solid, in grams, to prepare 1.000 L 0.02 M standard KMnO4 solution? It turns out that 38.37 mL of 0.0198 M KMnO4 is required to titrate a solution made from 0.6128 g of iron ore. What is the mass percent of iron in the iron ore?

Quest 1 – Mass Percent of Iron in an Ore
The iron content of iron ore can be determined by titration with standard
KMN0, solution. The iron ore is dissolved in HCI, and all of the iron is reduced
4
to Fe2+ ions. This solution is then titrated with KMNO, solution, producing Fe3+
and Mn2+ ions in acidic solution. What is the mass of KMNO, solid, in grams, to
prepare 1.000 L 0.02 M standard KMN0, solution? It turns out that 38.37 mL of
0.0198 M KMNO, is required to titrate a solution made from 0.6128 g of iron
ore. What is the mass percent of iron in the iron ore?
