Abstract
A kinetic study of the reactions I^−^ + S~2~O~8~^=^ and CV^+^ + OH^−^ (CV = 4, 4′, 4″‐tris(dimethylamino)triphenylmethyl chloride or crystal violet) in different water in oil microemulsions is reported. The dependence of the rate constants on the nature of the surfactant as well as on the molar ratio R = [H~2~O]/[Surfactant] has been investigated. The results are interpreted on the basis of the electrostatic interactions between the reactants and the surfactant polar heads and considering the water properties inside the aqueous core of the droplets.
