Purpose:
The purpose of this experiment is to determine the molarity of a permanganate solution through the use of redox titration.

Theory:
The following are the reactions that take place in the experiment:
Unbalanced: H2C2 O4 (aq) + MnO4- (aq)  CO2 (g) + Mn2+(aq)
H2C2 O4 Half-Reaction: H2C2 O4 (aq)  2CO2 (g) + 2e- + 2H+(aq)
MnO4- Half-Reaction: 8H+ + 2MnO4-(aq) + 5e-  Mn2+(aq) + 4H20 (l)
Net Reaction: 5H2C2 O4 (aq) + 6H+ + 2MnO4- (aq)  10CO2 (g) + 2 Mn2+(aq) +8H20 (l)
The solution was heated in order to reach better reaction rates, since the reaction occurs slowly at room temperature. Unlike many other titrations no indicator is necessary to tell the experimenter when the endpoint of the reaction is. In this case, the experimenter knows when all the oxalate has been consumed because the excess of permanganate will show up as a pink color. Thus, the permanganate ion acts as an indicator itself. The reaction produces its own......
