The Reaction Between Oxalate Ion with Permanganate
Description: A sample of sodium oxalate in dissolved in sulfuric acid. The solution is heated and then titrated with potassium permanganate to a pink endpoint.
5Na2C2O4(H+) + 2KMnO4(aq) + 8H2SO4(aq) + → 10CO2(g) + 8H2O(l) + 2Mn+2(aq) +10 Na+(aq) + 2K+(aq) + 8SO4-2(aq)
