SOLVED: A sample of 1.55 g of iron ore is dissolved in an acid solution in which the iron is converted into Fe2 . The solution formed is then titrated with KMnO4, which oxidizes Fe2 to Fe3 while the MnO4- ions are reduced to Mn2 ions. 92.95 mL of 0.020 M KMnO4 is required for the titration to reach the equivalence point.a) Write the balanced equation for the titration.b) Calculate the percentage of iron in the sample.
