“…Whereas viscosity of electrolyte solutions has been widely studied in water and organic solvents, 1,2 less consideration has been devoted to solutions in solvent mixtures. A survey of the literature on the viscosity data of electrolytes solutions in aqueous mixtures with organic solvents shows that they were determined mostly for 1,1 type of electrolytes and usually at one or only several temperatures in aqueous mixtures of formamide, 3,4 N,N-dimethylformamide, 5 dimethylsulfoxide, 6 acetone, 7 dimethylacetamide, 8 2-ethoxyethanol, 9 methanol, 10,11 ethylene glycol 12,13 and tert-butanol. 14 Among aqueous mixtures water-1,4-dioxane mixtures permit the widest variation of the solvent permittivity ranging from 2.21 to 78.36 in pure 1,4-dioxane and in water at 298.15 K, respectively.…”
