Problem- The reaction of MnO4^? with oxalic acid (H2C2O4) in acidic solution, yielding Mn^2+ and CO2 gas, is widely used to determine the concentration of permanganate solutions.
A) Write a balanced net ionic equation for the reaction.
B) Use the data in Appendix D in the textbook to calculate E? for the reaction.
C) and D) Show that the reaction goes to completion by calculating the values of ?G? and pK=?log(K) at 25 ?C
E) A 1.325g sample of sodium oxalate (Na2C2O4) is dissolved in dilute H2SO4 and then titrated with a KMnO4 solution. If 30.95mL of the KMnO4 solution is required to reach the equivalence point, what is the molarity of the KMnO4 solution? State your answer using four significant figures.
