ABSTRACT

The viscosities and densities of rubidium bromide were determined in dimethyl sulfoxide (DMSO) + H2O mixtures of different compositions as a function of concentration [(0.01 to 0.06) mol*L-1] and temperatures [(25 to 45) deg C] to obtain the Jones-Dole B-coefficient. The positive values indicated that the salt behaved as a structure maker in DMSO, and in DMSO + H2O mixtures, the B-coefficient values were less positive, showing a weak structure-making effect. On the other hand in H2O, B-coefficient values of RbBr were negative, showing the structure-breaking ability.
