Diffusion Coefficients in Aqueous Solutions of Beryllium Sulfate at 298 K

Abstract

Differential diffusion coeficients of beryllium sulfate in water at 298 K and at different concentrations have been measured using a conductimetric cell. The results are discussed on the basis of the Onsager- Fuoss theory. The results were interpreted with success, using the developments introduced by Pika1 in the above theory. The cell uses an open-ended capillary method, and a conductimetric technique is used to follow the diffusion process by measuring the resistance of a solution inside the capillaries at recorded times.
