5C2O4^2- + 2MnO4^- ==> 2Mn^2+ + 10CO2
I know that doesn't balanced the equation and if you wish to add the H^+ on the left and H2O on the right I recommend it; however, the redox part is balanced and that is all that is needed to work the problem. Your prof may want you to completely balance the equation.
mols KMnO4 = M x L = ?
Using the coefficients in the equation above, convert mols KMnO4 to mols H2C2O4.
Then M H2C2O4 = mols H2C2O4/L H2C2O4. You know L and mols, solve for M.
100mL of oxalic acid (H2C2O4) requires 35mL of 0.04M KMnO4 to titrate it to the endpoint. calculate the molarity of the oxalic acid.
