The Fe2+ content of iron tablets was determined by titration with a freshly standardised solution of potassium manganate(VII), KMnO4. The equation for the titration reaction is 5Fe^2+ + MnO4^-+ 8H^+ → 5Fe^3+ + Mn^2+ + 4H2O (e) Describe how exactly 250 cm3 of Fe2+ solution was prepared from five iron tablets, cach of mass 0.392g Why was some dilute sulfuric acid used in making up this solution? (e) On average, 22.76 of 0.005 M potassium manganate(VII) was required to react with 25.0 cm3 portions of the iron solution prepared from the five tablets. Calculate (i) the molarity of the Fe3+ solution, (i) the total mass of iron in the 250 cm3 of solution, (iii) the percentage by mass of iron in the tablets.
