Standardize a solution of KMnO4 by titration with a solution of oxalic acid. Weight out 1.378g H2C2O4•2H2O also dissolve it with deionized water in a 25.00 mL volumetric flask.
1. Explain what is the molarity of this oxalic acid solution?
2. Define what is the balanced overall net-ionic equation for the reaction between oxalic acid and the permanganate ion, MnO4-?
3. State what is the molarity of the KMnO4 solution if it requires 15.42 mL of KMnO4 solution to reach the endpoint in a titration with 10.00 mL of the oxalic acid solution?
