Precise resistivity n ( cm) and viscosity c (10.2 P) measurements for isobutyric acid water (IBAW) critical mixtures with added K+ and Cl. ions have been performed in the Arrhenius temperature domain of the electrolyte. From the activation energy, the resistivity viscosity relation reveals a fraction power character over the whole range of parameters investigated. To analyze our data we have used an exponential formula derived from the equivalent Arrhenius law: n/T is proportional to (c/T)R, where R = En/Ec is the ratio between the resistivity and viscosity activation energies. In the case of the pure system (IBAW), the value of R is in vicinity of 1, but when the salt is added, the ratio R shows dependence on the (K+, Cl.) concentrations: 0.6 less than R less than 1. The domain of the validity of R is in conformity with the theoretical prediction. The Coulombic interaction is the origin of the deviation.
