a quantity of 25 ml of a solution containing both Fe2+ and Fe3+ ions is titrated with 23 ml of .02 M KMnO4 solution. as a result all the Fe2+ ions are oxidised to Fe3+ ions. Next the solution is treated with Zn metal to convert all Fe3+ ions to Fe2+ ions. Finally, the solution containing only the Fe2+ ions requires 40ml of the same KMnO4 solution for oxidation to Fe3+. Calculate the molarity of Fe2+ and Fe3+ in the original solution.
