3. Results and discussion
The experimental values of physical properties of the pure solvents
were in good agreement with those found in the literature, as in
Table 1 where appropriate corrections were made by the specific
conductance of the solvents at that temperature.
The specific conductance (κ, mS cm−1
) of the electrolyte (IL) solutions
under investigation with a molar concentration within the range
of 1.13 × 10−4
–1.04 × 10−3 (M) in different solvents was measured.
The molar conductances (Λ) for all studied solution system have been
calculated using the appropriate equation [4].
The values of equivalent conductance (Λ0) at various concentrations
are represented in Table 2 and the conductance data for 1-ethyl-3-
methyl imidazolium methanesulfonate in n-propanol, n-butanol, and
n-pentanol have been investigated using the Fuoss conductance
equation [5].
Three adjustable parameters namely the limiting molar conductance
Λ0, the association constant (KA) and the distance of closest approach of
