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 the concentration of one ...SUMMARY The ORP value only tells you if an oxidation-reduction reaction CAN happen.
