Other Kinds of titrations are possible in addition to acid-base titrations. For example, the concentration of a solution of potassium permanganate, KMnO4, can be determined by titration against a known amount of oxalic acid, H2C2O4, accoiding to the following equation:
5H2C2O4(aq) + 2KMnO4(aq) + 3H2SO4(aq) ---> 10CO2(g) + 2MnSO4(aq) + K2SO4(aq) + 8H2O(l)
What is the concentraton of KMnO4 solution if 22.35mL reacts with 0.5170g of oxalic acid.
