1.) Sodium oxalate, Na2C2O4, in solution is oxidized to CO2(g) by MnO−4 which is reduced to Mn2+. A 50.0 −mL volume of a solution of MnO−4 is required to titrate a 0.342 −g sample of sodium oxalate. This solution of MnO−4 is then used to analyze uranium-containing samples. A 4.60 −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+→UO2+2. Calculate the percentage of...

7) (10 pts) In the titration of sodium oxalate with potassium permanganate, very pure sodjum oxalate (Na2C2O4, MM133.9985 g/mol) is used to find an accurate Molarity of a potassium permanganate (KMnO) solution. If 98.52 mg of sodium oxalate is dissolved in exactly 25.00 mL of solution at 25.0°C, 21.50 mL of KMnO solution is needed to achieve equivalence. What is the Molarity of the KMnO,? Sodium and potassium ions are spectators in this reaction. Constant normal Ts and Ps are...
