Ionic viscosity B-coefficients of tetraalkyl ammonium chlorides in (0 to 100) mass % water plus methanol at 298.15 K
The viscosities of tetraalkylammonium chlorides, R4NCI (R = -CH3 through n-C4H9), have been measured in (0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100) mass % aqueous methanol at 298.15 K. By using the Jones-Dole equation, the corresponding B-coefficients have been calculated. The ionic B-values have been determined using the "reference electrolyte" KCI. Solvation number (n(a)) values have been used to discuss the solvation of ions.
