• The reduction of 2, 6-dichlorophenolindophenol (DCIP) by aromatic reductones was studied in the range of pH 2.3 to 8.6, using stopped-flow apparatus. The apparent first-order rate constant, kapp, and the second-order rate constant, k, of the reaction were determined. The k-pH profile was considerably different from that of L-ascorbic acid. The logk of DCIP reduction in a solution of 50%ethanol was found to depend linearly on Hammett's σp value.
