1 A sample of a Fe2+ solution requires 26 mL of 0.0200 M K2Cr2O7 for a reaction in which Fe2+ is oxidized to Fe3+ and Cr2O72-is reduced to Cr3+ . An identical sample of the same Fe3+ solution requires 41.6 mL of KMnO4 solution for a reaction in which Fe2+ is oxidized to Fe3+ and MnO4- is reduced to Mn2+ .What is the normality of K2Cr2O7 solution? Select one: a. 0.100 b. 0.1300 c. 0.1200 d. 0.1400
