摘要:

The electrochemical reduction of 2,2′-bipyridine (bipy) complexes of cobalt (II), [Co(bipy)3]2+, in aqueous medium has been studied with dc tast, normal pulse polarography and controlled-potential coulometry. The cathodic wave in the process [Co(bipy)3]2+/[Co(bipy)3]+shows catalytic character in the presence of hydrogen ions. The rate constant of the parallel chemical reaction was found to be 2.2 × 104M−1. s−1.
