Sodium oxalate, Na2C2O4, in solution is oxidized to CO2(g)
Chapter 18, Problem 133E(choose chapter or problem)
Sodium oxalate, Na2C2O4, in solution is oxidized to CO2(g) by MnO4-, which is reduced to Mn2+. A 50.1 mL volume of a solution of MnO4- is required to titrate a 0.339 g sample of sodium oxalate. This solution of MnO4 - is used to analyze uranium- containing samples. A 4.62 g sample of a uranium containing material requires 32.5 mL of the solution for titration. The oxidation of the uranium can be represented by the change UO2+ UO22+. Calculate the percentage of uranium in the sample.
