The viscosities and densities of solutions of nine alkali halides (lithium, sodium, potassium, rubidium, and cesium chlorides; sodium fluoride, bromide and iodide; cesium iodide) and four quaternary ammonium bromides (tetramethyl, tetraethyl, tetra‐ n ‐propyl and tetra‐ n ‐butyl) have been measured over the concentration range 0.05–0.25 N in dioxane‐water mixtures containing 0–63 weight % dioxane. The Jones‐Dole B ‐coefficient for the alkali halides increases as the dioxane fraction increases, to values much larger than those corresponding to the Einstein volume effect, suggesting a selective solvation of the cations. With increasing dioxane fraction, the B ‐coefficients for the quaternary salts tend towards the theoretical values calculated from the known crystallographic radii of their ions.
