The reduction of mer-tris-picolinatoruthenium(III) by L-ascorbic acid as a function of pH can only be studied under well-selected reaction conditions to prevent the back-oxidation of tris-picolinatoruthenium(II) caused by traces of dioxygen. Under such conditions, the redox activity of L-ascorbic acid (AscH2) follows the sequence AscH2 << AscH– << Asc2–.
