On the molar volumes and viscosities of electrolytes

The b (V) coefficient of the term linear with the concentration of the apparent molar volume V-phi of electrolytes in water and several non-aqueous solvents is examined. Its relationship with the B (eta) coefficient of the corresponding term in the relative viscosity of these electrolyte solutions is explored. Positive correlations are found in some cases as expected, but in others, where crowding of the solvation shells occurs on increasing concentration, such correlations fail.
