Multiple Choice
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?
A) 0.02914 M
B) 0.4312 M
C) 0.1821 M
D) 0.3152 M
E) 0.05044 M
