2MnO4- (aq) + 5H2C2O4(aq) + 6H+(aq)  →  2Mn+2(aq)  + 10CO2(g) + 8H2O(l)

In a titration experiment, a 0.040 M solution of KMnO4(aq) is added from a buret to an acidified sample of H2C2O4(aq) in a flask with a volume of 20 mL.  The endpoint of the titration is determined by the appearance of a faint pink color in the mixture.  The initial buret reading is 6.09 mL and the final buret reading is 26.09 mL.  

  1. Identify the analyte and the titrant. 
  2. Identify the element oxidized and the element reduced.  Justify your answer using oxidation numbers. 
  3. Calculate the concentration of the H2C2O4 sample.
