Evaluate the mass percent of iron in the ore

Reference no: EM13538958

The mass percent of iron in an iron ore can be determined by converting Fe to Fe2+ in acid solution, and then titrating the dissolved sample with KMnO4 solution. A 2.51 g ore sample dissolved in acid required 28.62 mL of 0.0821 M KMnO4 to reach the equivalence point. Calculate the mass percent of iron in the ore.
