On the estimation of equivalent conductivity of electrolyte solutions; The effect of relative static permittivity and viscosity
Abstract
The effect of a concentration-dependent relative static permittivity(RSP) and viscosity on the predictions of the equivalent conductivitymodels is studied. The full version and simplified version of the meanspherical approximation models along with four Debye-Hückel-Onsager(DHO) based equivalent conductivity models are used to predict theequivalent conductivity of nine 1:1 aqueous electrolyte solutions at25°C. Three of the DHO based models have been developed in this study bycombining the electrophoretic and relaxation effects that have beenpreviously presented in the literature. To investigate the effect of RSPon the equivalent conductivity predictions, we have used threeempirical RSP models along with the solvent's RSP. It has been shownthat using a concentration-dependent RSP reduces the deviation ofequivalent conductivity predictions from the experimental data. We havealso investigated the effect of a concentration-dependent viscosity onthe equivalent conductivity predictions. Our observations show thatusing a concentration-dependent viscosity sometimes improves andsometimes worsens the predictions.
