The concentration of oxalate ion (C2O42-) in a sample can be determined by titration with a solution of permanganate ion (MnO4-) of known concentration. The net ionic equation for this reaction is 2MnO4- + 5C2O42- + 16H+ --> 2Mn2+ + 8H2O + 10CO2 A 30.00 mL sample of an oxalate solution is found to react completely with 21.93 mL of a 0.1725 M solution of MnO4-. What is the oxalate ion concentration in the sample?
