Warburg impedance is a well-known term in the field of impedance spectroscopy because of the early date at which it was published, the formulation came before the rest of the properties of the interface were known. In fact, for nearly all real situations examined in electrochemistry, the Warburg impedance is relatively small. Thus, for a concentration of 1 mol liter and a frequency of 1 kilocycle s l, and using the normal parameters for room temperature, the resistance is in the milliohm cm-2 range. 

ILs are regarded as a new generation of catalysts in the chemical industiy, with several uses in different commercial segments. The ILs are used in chemistiy as solvents in organic synthesis, catalyzed reactions, electrochemistry and spectroscopy, and room-temperature chemistry. Seddon et al. reported ILs as nonaqueous polar-like solvents for electrochemical and spectroscopic studies of transition metal complexes [26]. ILs used in liquid-liquid extractions form abiphasic liquid system with water.
