Abstract The viscosities of most alkali and tetraalkylammonium halides have been measured in water at 25°C. The relative viscosities can be fitted, up to 1M, with the relationη r =1+A η c1/2+B η c+D η 2. TheA η term depends on long-range coulombic forces, andB η is a function of the size and hydration of the solute. When combined with partial-molal-volume data, the difference B η −0.0025V° is mostly a measure of the solute-solvent interactions. IonicB η are obtained if the tetraethylammonium ion is assumed to obey Einstein's law. TheD η parameter depends on higher terms of the long-range coulombic forces, on higher terms of the hydrodynamic effect, and on structural solute-solute interactions. As such, it cannot be interpreted unambiguously.
