In order to standardize a KMnO4 solution, 0.3301 g Na2C2O4 was dissolved in 30 mL water and 15 mL 3.0 M H2SO4. The KMnO4 solution was added to the Na2C2O4 solution until a pale pink color persisted. The titration took 31.1 mL of KMnO4 solution. What is the concentration of the KMnO4 solution?
I know that I'm probably going to have to start with a net ionic equation for the first addition of Na2C2O4 and H2SO4 with the sulfuric acid acting as the polyprotic acid. Would I first have to convert to moles, and then figure out the concentration of the ions formed that will react with KMnO4 in the next reaction?? But then how do I write the equation and solve the equilibrium after the KMnO4 has been added?
