Experiments performed with the closed-capillary technique are used to investigate diffusion coupling processes in multicomponent aqueous electrolytes. The transient effects observed on the sulfate (SO4 2-) ion during the migration of LiCl and NaCl are compared with theoretical predictions based on solutions of the diffusion equations. These equations are solved by using normal-mode analysis and finite-difference calculations and the influence of ionic association is considered explicitly.
