Question:

Permanganate ions are powerful oxidizing agents used in water treatment facilities to remove metals, such as iron, and toxic and malodorous chemicals, such as H₂S. If you are using permanganate solutions, you need to know the exact concentrations. Titration with oxalic acid is commonly used to determine the concentration of solutions of MnO₄ ^–, so you need to know the balanced redox equation. Permanganate ions, MnO₄ ^–, oxidize oxalic acid, H₂C₂O₄, in acidic aqueous solution. The skeletal equation (with states added) for the reaction is

Write the balanced net ionic equation for this reaction.
