Webbreduction reaction will depend on pH if the ORP of the oxidant or reductant is pH dependent. The following titration curve (see Graph 2) shows the ORP of the reaction of hypochlorous acid and bisulfite ion. The half-reactions for both of the redox couples are pH dependent. The titration curves for each pH are offset, but retain the same basic form. Webb19 juli 2024 · pH Meter Principle, Calibration, and Working. July 19, 2024 by Naresh Bhakar.
