The iron content of iron ore can be determined by titration with a standard KMnO4 solution. The iron ore is dissolved in HCl, and all the iron is reduced to Fe²+ ions. This solution is then titrated with KMnO4 solution, producing Fe³+ and 3+ Mn²+ ions in acidic solution. If it required 34.08 mL of 0.0510 M KMnO4 to titrate a solution made from 1.957 g of iron ore, what is the mass percent of iron in the iron ore? Mass percent = %
A 4.510 g rock sample is dissolved in strong acid and treated with a reducing agent so that all the iron is completely transformed into Fe2+. The Fe2* is completely oxidized by 28.10 mL of a 0.0530 M solution of KMNO4. Calculate the amount of iron (in grams) and its mass percentage in the rock sample.
