The redox reaction between KMNO, and Na,C,O, is shown in equation 1 of the Introduction. A solution of KMNO, is titrated into 15.0 mL of Na,C,O, until the solution turns light pink. The concentration of the Na,C,0̟ is 0.75 N, and the volume of the potassium permanganate added is 16.7 mL. Calculate the normality of the KMNO, solution.

Expert Solution
Step 1

The reaction taking place between KMnO4 and Na2C2O4 can be written as,

=> 5 Na2C2O4 + 2 KMnO4 + 8 H2SO4 → K2SO4 + 5 Na2SO4 + 2 MnSO4 + 10 CO2 + 8 H2O

Given : Normality of Na2C2O4 = 0.75 N

Volume of Na2C2O4 solution = 15.0 mL

And volume of KMnO4 solution = 16.7 mL
