Limiting Molar Conductivity Dynamics of κcar/PEO/NaClO4 Aqueous Electrolyte System at Different Temperature

Year: 2024

Type: article

Abstract: The limiting molar conductivity behaviour (Λo) of κcar/PEO/NaClO4 blend liquid electrolyte systems in aqueous solution at 20 and 25 ºC was studied. The ionic conductivity (κ) of the electrolyte system was measured using Mettler Toledo Seven Compact S230 AC conductivity meter. The κ of the electrolyte was measured at a range of salt concentration, Csalt (10-5-10-8) and at different polymer concentration, Cpoly (0.001-0.003 g cm-3). The data analysis showed a directly proportion relation between Λo and Cpoly, which indicates a decrease in total salt dissociation (α) and consequently, an increase in the formation of ion pairing occurs due to the increase in salt dissociation and less dynamic volume. In addition, a direct relation between Λo and temperature was also observed. An increase in temperature causes a decrease in the total ion pairing while increase the ion movement.
