Experimental (a) dynamic viscosity, η, and (b) electrical conductivity, κ, for LEV:[N4444]Cl(2:1) DES as a function of temperature. Panel (c) reports Walden plot showing the log–log plot of molar conductivity, Λ, vs fluidity, η^–1 (where η stands for dynamic viscosity). Panel (d) shows the calculated percentage of ionicity as inferred from eq 6. VFT fit parameters of experimental viscosity are reported in panel (a). Dashed line in panel (c) shows the reference theoretical behavior of 0.01 M KCl solution. A red arrow in panel (c) shows increasing temperature.
