title: Electrolyte diffusion of cesium bromide in water at 25 degrees C.
abstract: Electrolyte diffusion coefficients of CsBr in water have been measured using 137Cs isotope with an open ended capillary technique without stirring. The measurements were done at 25 degrees C over the concentration range of 10(-6) -0.25 M and the measured values are compared with the theoretical values of diffusion coefficients estimated on the basis of Onsager-Fuoss theory. At low concentrations, there is a good agreement between the experimental and theoretical values of diffusion coefficients. The deviations at higher concentrations are explained on the basis of the occurrence of ion-ion interactions.
