A solution of iron (II) sulfate was prepared by dissolving 10.00g of FeSO4-7H20 (FW= 277.9) in water and diluting up to a total volume of 250 ml. The solution was left to stand, exposed to air, and some of the iron (II) ions became oxidized to Iron (III) ions. a 25.0 ml sample of this partially oxidized solution required 23.70 ml of 0.0100M potassium dichromate K2Cr2O7 solution for complete reaction in the presence of dilute sulfuric acid. Calculate the percentage...

- Solving applied mass percent problems Iron(II) sulfate forms several hydrates with the general formula FeSO, XH,O, where x is an integer. If the hydrate is heated, the water can be driven off, leaving pure FeSO, behind.
