Titration of 50.00 mL of 0.0521 M sodium oxalate, Na2C2O4, required 38.71 mL of a potassium permanganate solution:

5 C2O42- + 2MnO4- + 16H+ = 2Mn2+ + 10 CO2 + 8H2O
Calculate the molarity of the potassium permanganate solution.

1 answer

mols Na2C2O4 = M x L = ?
Use the coefficients in the balanced equation to convert mols Na2C2O4 to mols KMnO4.
Then M KMnO4 = mols KMnO4/L KMnO4
