Viscosity studies on lithium bromide in water plus dimethyl sulfoxide mixtures at 278.15 K and 293.15 K

Viscosities of dilute solutions of lithium bromide in binary mixtures of water + dimethyl sulfoxide (DMSO) have been measured in the composition range 0-85 mass % DMSO at 278.15 K and 0-100 mass % DMSO at 293.15 X. The viscosity data have been analyzed by the Jones-Dole equation. The viscosity B coefficients of LiBr are positive at both temperatures in the whole composition range of the mixed solvent. The ion-solvent interactions have been discussed.
