An iron ore is analyzed for iron content by first dissolving it in an acid, converting the iron to Fe2+. The Fe²+ solution is then titrated with Cr2072 solution. During the redox titration, Fe2+ is oxidized to Fe3+ and Cr20 2- is reduced to Cr3+. If 35.6ml of 0.0150 mol/dm standard K2Cr2O7 is required to titrate the iron in a 1.68g of iron ore, what is the percentage of iron in the ore? Given: 1dm = 1liters Cr20,2 +14 H+ + 6 Fe2+ + 2 Cr3+ + 6 Fe3+ + 7 H20
