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.
considering this given equation as 2no o2 --gt 2no2 this is believed to occur by the mechanism 2no--gt n2o2
