4. The redox reaction between KMNO4 and Na,C,O is shown in equation 1 of the Intro- duction. A solution of KMNO4 is titrated into 15.0 mL of Na,C,O4 until the solution turns light pink. The concentration of the Na,C,O, is 0.75 N, and the volume of the potassium permanganate solution. added is 16.7 mL. Calculate the normality of the KMnO4 enoil 5.14.6 mL of 0.15 N KMNO4 solution was added to completely oxidize the sodium oxalate in a 0.50 g mixture of Na2C,04 and NaCl. (NaCl does not react with KMNO4.) Calculate the mass percent of Na2C04 in the mixture.
