Question

I need help calculating the initial and final concentrations of Oxalic Acid and Permanganate. The concentration of Oxalic Acid used was .7550 M and .1300 M for Permanganate.

3H2C2O4(aq) + 2MnO4-(aq) --> 6CO2(g) + 2MnO2(s) + 2OH-(aq) + 2H2O (l)

For each experiment calculate the initial and final concentrations of Oxalic Acid and Permanganate.

Please show your work so that I know how to solve problems like this in the future.

Experiment Number H2O Volume Used Oxalic Acid Volume Used KMnO4 Volume Used 1 6 mL 5 mL 1 mL 2 1 mL 10 mL 1 mL 3 5 mL 5 mL 2 mL

Explanation / Answer

Permanganate, 158.034 g/mol

0.001L*0.1300mol/L=0.00013mol KMnO4

0.00013mol/.012 L = 0.011M

Oxalic Acid,

0.005L*0.17550mol/L=0.00088 mol

0.00088 mol/.012 L = 0.073125 M
