Salt effects on the reactions [Fe(CN) 6 ] 4− + S 2 O = 8 and [Ru(NH 3 ) 5 py] 2+ + S 2 O = 8have been studied in media of different dielectric constants constituted by mixtures of water with organic cosolvents. It is known that salt and solvent effects are coupled and, consequently, cannot be treated separately. This implies that salt (and solvent) effects need to be carefully analyzed before using them as a tool for mechanistic discrimination. © 2009 Wiley Periodicals, Inc. Int J Chem Kinet 41: 582–588, 2009
