The ionic conductivity of the mixture of RTILs and EG was estimated with the highthroughput setup discussed in the Experimental Methods section at 298.15 K. The relative ionic mobility comprised of ion dissociation is calculated with the help of Eq. ( ) to compare its trend with ionic mobility. The ionic conductivity and relative ion dissociation (ξr) behavior of the RTIL system consisting of imidazolium cation ([EMIM] + , [BMIM] + , [HMIM] + , and [OMIM] + with tetrafluoroborate anion ([BF4] -) in EG is shown in Figure (a), and 3(b), respectively. It could be observed that the conductivity increases with the increase of the ionic liquid mole fraction, reaching a maximum and then decreases approaching the conductivity of the neat RTIL. Also, as the alkyl chain length increases, the ionic conductivity behavior of the respective RTIL system decreases, similarly observed for neat RTILs conductivity. Therefore, this RTIL system has the following trend of ionic conductivity,
