Ethylene Carbonate, (EC), has relatively high dipole moment and relative permittivity but its high freezing point (300C) has put several restriction on the use of EC directly as solvent for electrochemical studies. EC + water mixtures are more convenient for particular utilization, as they are miscible at various proportions (Viz 20, 40, 60 and 80 mass% EC + Water) at 250C with relative permittivity higher than that of water. With this background some conductance studies of monovalent salts were undertaken in these solvents. From the resulted limiting molar conductivity values the limiting ionic conductivity of some ions is reported in 20, 40, 60 and 80 weight% EC + Water at 250C.

Abstract


Ethylene Carbonate, (EC), has relatively high dipole moment and relative permittivity but its high freezing point (300C) has put several restriction on the use of EC directly as solvent for electrochemical studies. EC + water mixtures are more convenient for particular utilization, as they are miscible at various proportions (Viz 20, 40, 60 and 80 mass% EC + Water) at 250C with relative permittivity higher than that of water. With this background some conductance studies of monovalent salts were undertaken in these solvents. From the resulted limiting molar conductivity values the limiting ionic conductivity of some ions is reported in 20, 40, 60 and 80 weight% EC + Water at 250C.
