1. Determine the molarity of the KMnO4 solution if 26.23mL of potassium permanganate solution is required to titrate 1.041 g of ferrous ammonium sulfate hexa-hydrate,
FeSO4 (NH4)2 SO46H2O.
2. Determine the %Fe in the unknown if a 2.893g sample of an unknown containing iron requires28.45 mL of the permanganate solution described above to reach the endpoint.
