Chapter 7, Problem 7.127CHP
A mixture of FeCl2 and NaCl is dissolved in water, and addition of aqueous silver nitrate then yields 7.0149 g of a precipitate. When an identical amount of the mixture is titrated with MnO4−, 14.28 mL of 0.198 M KMnO4 is needed for complete reaction. What are the mass percents of the two compounds in the mixture? (Na+ and Cl− do not react with MnO4−. The equation for the reaction of Fe2+ with MnO4− was given in Problem 7.126.)
