he decrease in conductance value is comparatively more than the
increase in viscosity value leading to higher Walden product of salt in
propanol compared to other two solvents.
Limiting ionic conductance λ±o, ionic Walden product λo
±η, Stokes'
radii rs, and crystallographic radii rc are presented in Table 6. Plot of
limiting ionic conductance (λ±o) of [emim] CH3SO3, ionic Walden
product (λ±
oη) of [emim]+ and (CH3SO3)
− is represented in Fig. 1.
The diffusion coefficient (D) is obtained using the Stokes–Einstein
Relation [11].
