The estimation of iron(II) and iron(III) in a mixture containing both I have been given a solution that contains between 1.1g and 1.3g of iron ions; they are in a mixture of both Fe2+ and Fe3+. My aim is to work out the percentage of each of them in the solution. With my research I have found out that the best method would be to find out how many grams of Fe2+ ions there are first. I must then convert all the Fe3+ ions in to Fe2+ ions by reducing them with granulated zinc and H2SO4. This would enable me to then work out the total mass of all the iron ions in the solution. Total Mass - Mass of Fe2+ = Mass of Fe3+ After I know the mass of each different iron ion in the solution I can then convert these into percentages. Equipment 200cm3 of Fe2+/Fe3+ solution H2SO4 (1 mol dm-3) KMnO4...
