Abstract
The diffusion coefficients of sodium salts of m-benzene disulfonate, 1,5-naphthalenedisulfonate, 1,2-ethanedisulfonate, and 1,4-butanedisulfonate in aqueous solutions were measured at 25°. The concentration dependence of the diffusion coefficients for sulfonates decreased with increasing charge distance and was smaller than that of the corresponding ordinary 2 : 1 electrolytes. The concentration dependence of diffusion coefficient for sodium m-benzenedisulfonate was the largest. It is shown that bolaform electrolytes behave like normal 1 : 1 electrolytes in the concentration range where the ion atmosphere around each charged group is independent.
