Experimental - Redox titrations - analysis of iron(II)Deze pagina vertalen

Data processing. Moles of manganate(VII) = 0.01 x 0.01 = 0.0001 mol. Therefore, from the reaction stoichiometry, moles of iron(II) = 5 x 0.0001 = 5.00 x 10-4 mol. This is in 27.90 ml, therefore in 250 ml there is (250/27.9) x 5.00 x 10-4 = 8.96 x 5 x 10-4 moles of iron = 4.48 x 10-3 mol. Therefore mass of iron in 250 ml = 56 x 4.48 x 10-3 g = 0.25 g. Hence, mass of iron per tablet = 250 mg
