1. Introduction
An ionic liquid (IL) is an electrolyte in the liquid state or phase,
whose melting point is below some arbitrary temperature, such as
100 °C. In general, ionic liquids (ILs) are liquid electrolytes that consist
of combinations of organic–organic or organic–inorganic cation/anions.
Because of their unique physicochemical properties, such as the
favorable solubility of organic and inorganic compounds, low vapor
pressures, low melting points, high thermal stability, good solvent
characteristics for organic, inorganic and polymeric materials, adjustable
polarity, selective catalytic effects, chemical and thermal stability,
non-flammability and high ionic conductivity, ionic liquids have generated
significant interest in a wide range of industrial applications [1].
Ionic association of electrolytes in solution depends upon the mode
of solvation of its ions which in turn depends on the nature of the
solvent/solvent mixtures. Such solvent properties as viscosity and the
relative permittivity have been taken into consideration as these
properties help in determining the extent of ion association and the
ion–solvent interactions. The association and solvation behavior of
ions in solution is obtained from the conductance measurement.
Along with our investigation on electrical conductance of electrolyte
the present work deals with the transport and thermodynamic properties
of 1-ethyl-3-methylimidazolium methanesulfonate in n-propanol,
n-butanol and n-pentanol at 298.15 K. Study on the transport properties
of electrolytes in different solvent media are of great importance to
