CHEMISTRY LAB QUESTION!??!?
Oxalic acid (H2C2O4) found in dark leafy, green vegetables such as spinach, can inhibit iron absorption in the body. To determine the concentration of oxalic acid in a food, one can titrate a sample with a permanganate solution, which changes color on reaching the equivalence point. If one cup of spinach contains 180 mg of oxalic acid, how many milliliters of 0.0100 M permanganate solution would be required to reach the equivalence point? The balanced equation is given here.
HCO(aq)+MnO (aq)⎯⎯→2CO(g)+Mn (aq) 22442

If this keeps up, why bother graduating at all?
Just lay back and let the boys pay you for it.
Right?
