In this work, the effect of concentration (0.05-0.3 %w/w), PEG molecular weight and type of cation on the n_D,η and ρ of the mention binary and ternary mixtures have been explored. Furthermore, the experimental measurements were applied to compute the refractive index deviation (Δn_D), viscosity deviation (Δƞ), the apparent specific volume (V_φ), excess molar volume (V^E) and excess Gibbs energy of activation for viscous flow〖ΔG〗^(≠E)) for the analysis of the behavior of the solutions. Δn_D and V^E were fitted to the Cibulka and a third-order Redlich–Kister polynomial models to estimate the interaction parameters. The intermolecular interactions between the mixing components were demonstrated by the obtained data from the calculated functions.
