Consider the reaction of sodium oxalate (Na2C2O4) and potassium permanganate (KMnO4) in acidic solution. The unbalanced equation is the following:

In an oxidation-reduction titration, the KMn04 from the buret reacts with Na2C204.

a. What is the balanced oxidation half-reaction?


b. What is the balanced reduction half-reaction?


c. What is the balanced ionic equation for the reaction?


d. If 24.6 mL of a KMnO4 solution is needed to titrate a solution containing 0.758 g of sodium oxalate (Na2C2O4), what is the molarity of the KMnO4 solution?
