Abstract
In this work the viscosities of KCl, NaCl, NaI, KNO3, LiNO3, NaBPh4 and Bu4NI solutions (from ~0.01 mol dm–3 to ~0.05 mol dm–3) in water (1) + dimethyl sulfoxide (DMSO) (2) binary mixtures with mole fractions of DMSO, x2 = 0.01, 0.02, 0.05, 0.075, 0.10 and 0.15, were determined at 298. 15 K. The viscosities measured were used to evaluate the viscosity B-coefficients by means of Jones-Dole's equation. The results obtained allowed us to determine the values of B± coefficients for individual ions using the assumption about the equality B(Bu4N+) = B(BPh4–). All the results have been discussed in terms of ion-solvent interactions.
