Web9.4.1 Redox Titration Curves. To evaluate a redox titration we need to know the shape of its titration curve. In an acid–base titration or a complexation titration, the titration curve shows how the concentration of H 3 O + (as pH) or M n + (as pM) changes as we add titrant. For a redox titration it is convenient to monitor the titration reaction’s potential instead of … WebPermanganate Titration Principle This method utilizes the reduction of potassium permanganate (KMnO4) by hydrogen peroxide in sulfuric acid. Scope of Application This method is suitable for measuring aqueous solutions of H2O2 ranging from 0.25 to …
