Abstract
Salt effects on the oxidation of the iron(II) complexes Fe(CN)~4~(bpy)^2−^, cis‐(CN)~2~(bpy)~2~ and Fe(bpy)~3~^2+^ by S~2~O~8~^2−^ as well as on the reaction Fe^2+^ + Co(NH~3~)~5~Cl^2+^ have been studied in concentrated electrolyte solutions at 298.2 K. We have gone from anion–anion to cation–cation reaction with the intermediate cases of anion–neutral and cation–anion reactions. Results show that the main cause of the kinetic salt effects observed is the interaction between supporting electrolytes and the solvent. © 1994 John Wiley & Sons, Inc.
