Question- A solution contains both iron(II) and iron(III) ions. A 50.00 mL sample of the solution is titrated with 35.0 mL of 0.280 M KMnO4,which oxidizes at Fe^2+ to Fe^3+. The permanganate ion is reduced to manganese (II) ion. Another 50.00 mL sample of the solution is treated with zinc, which reduces all the Fe^3+ to Fe^2+. The resulting solution is again titrated with 0.0280 M KnO4; this time 49 mL is required. What are the concentrations of Fe^2+ and Fe^3+ in the (original) solution?
