PART II: DETERMINATION OF THE MASS PERCENT OF IRON(II) SULFATE Minimize a REACTION EQUATION In the next part of the experiment, you used your standardized KMNO4 solution to determine the mass percent of iron(II) sulfate, FeSO4 · 7 H2O, in a sample of ground pill. Please use the dropdowns to balance the following reaction equation. MnO, Fe2+ H+ Reactants 1 5 8 Fe3+ Mn² 2+ + H2O Products 4 The complete reaction equation will show once the above questions have been completed. 2+ MnO4¯ + 5 Fe2+ + 8 H+ → Mn² + 5 Fe3+ + 4 H2O MASS OF GROUND PILL In the next titration, you used your standardized potassium permanganate solution as the titrant, and a solution of your ground pill as the analyte. Please complete the table below. Pill 1 Pill 2 Mass of boat and ground pill (g) 0.9672 0.9385 Mass of boat (g) 0.5720 0.5765 Mass of ground pill (g) 0.3952 0.3620 TITRATION DATA Please complete the table below. Pill 1 Pill 2 Initial burette reading (mL) 0.23 1.92 Final burette reading (mL) 17.46 19.78 Titre (mL) 17.23 17.86
