Explain what percentage of the ore was iron

Reference no: EM13514021

The iron content of iron ore can be determined by titration with standard KMnO4 solution. The iron ore is dissolved in excess HCl and the iron reduced to Fe+2 ions. This solution is then titrated with KMnO4 solution, producing Fe+3 and Mn+2 in acidic solution. If it requires 41.95 mL of 0.0205 M KMnO4 to titrate a solution made with 0.6128 g of iron ore, what percentage of the ore was iron?
