| Abstract: | A computer-aided technique based on Tast polarography is examined for the determination of kinetic parameters of electrode reactions. It is particularly useful for the investigation of unstable species because of the simple and rapid processing of data. Kinetic parameters of cobalt(III)—ammine complexes at mercury electrodes are given for [Co(NH3)6]Cl3, [Co(H2O)(NH3)5](ClO4)3, [Co(NO3)(NH3)5](NO3)2 [CoF(NH3)5](Cl04)2, [Co(C03)(NH3)5] NO3 ,cis-[Co(H2O)2(NH3)4] (Cl04)3 [Co(CO3)(NH3)4] NO3 · 0.5H20, [Co(ox)(NH3)4]Cl · H20, and NH4[Co(ox)2(NH3)2] · H2O, which are obtained in solutions containing 0.1 M acetate buffer and 0.005% gelatin at 25°C. |
