Twenty-five milliliters of iron (II) solution was prepared by dissolving 200 mg of iron (II) tablet in deionized water and acidified with 1.5 M sulfuric acid. It required 16.70 mL of 0.005 M KMnO4 solution to reach completion. Find the mass percentage (mg/g) of iron (II) in 200-mg iron (II) tablets? The MW of iron is 55.85 g/mol. If the reported mass percentage of the iron (II) tablet is 100 mg/g, is the iron (II) concentration of the tablet you tested within the permissible range of variation of +25% of the reported value?
