title: Studies on self and electrolyte diffusion in cesium halides.
abstract: The present paper deals with the determination of the self-diffusion coefficients of 134 Cs(+) ions in CsI, CsBr and CsCl over the concentration range of 5 x 10(-6)-0.01 M and of electrolyte diffusion coefficients of CsI, CsBr and CsCl (5 x 10(-5)-0.1M) labelled with 134 Cs(+) in 1% agar gel at 25 degrees C. These diffusion coefficients are compared with those expected from the Onsager-Fouss and Onsager's theory for electrolyte and self-diffusion, respectively. The disparity between the theoretical and experimental diffusion coefficients over the wide range of concentrations is accounted on the basis of various types of interactions occurring in the ion-gel-water system.
