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 … We begin by calculating the titration’s equivalence point volume, which, as we … 9.3.1 Chemistry and Properties of EDTA.
