Redox reactions pH dependent

The trans-dioxoosmium(VI) complexes have been found to show pH-dependent redox reactions 74, 75, 211). In acidic medium, the cyclic voltammogram of trans-[0sVI(L)(0)2]2+ showed a reversible three-electron couple and an irreversible one-electron couple. The Pourbaix diagram of fr[Pg.281]

Those based on the pH-dependent redox reaction between the metal and a stable oxide, i.e. antimony, iridium and palladium. 

Dealing with pH-dependent redox reactions, as e.g. the oxidation of Cl" to Cl2by permanganite at pH 3, the number of protons used and formed must be considered.
