Determination ofIronin anOreSample by Oxidation Reduction Titration Abstract: In this experiment, we determined the molarity of apotassiumpermanganate solution as well as the percentironinoresample. We used a redox titration in which the oxidizing agent permanganate will oxidize a standard amount of oxylate, from which we derived the molarity of thepotassiumpermanganate solution to

    In the current experiment, potassium dichromate, K2Cr2O7, is used as the titrant to determine the amount of iron in an ore sample. Since the potassium dichromate is ionized in solution, the redox reaction taking place during the titration can be written as: 6 Fe2+ + Cr2O72- + 14 H+ 6 Fe3+ + 2 Cr3+ + 7 H2O
