- Oxalic acid (H 2 C 2 O 4 ) is present in many plants and vegetables. In acidic solution, oxalic acid can be oxidized
by the permanganate ion (MnO 4 −) according to the following unbalanced equation.
a. Balance the equation.
b. In a redox titration, 15.0 mL of 0.100 M MnO 4 −fully reacts with 23.6 mL of a C 2 O 42 −solution. What
is the concentration of the oxalate ion?
