Volumetric and acoustic characteristics of a temperature-dependent aqueous solution of trisodium EDTA with EG, DEG and TEG

Abstract

The apparent molar volume$\left(V_{\varphi }\right)$ and apparent molar isentropic compressibility $\left(K_{\varphi ,s}\right)$ of ethylene glycol (EG), diethylene glycol (DEG) and triethylene glycol (TEG) in trisodium ethylenediaminetetraacetic acid solution (aqueous) have been estimated based on measured experiments values for both the density $(\rho$) and sound speed (s) at (288.15, 298.15, 308.15 and 318.15) K and 0.01 MPa as well. From the foundation in infinite dilution limiting apparent molar volumes $\left(V_{\varphi }^{{}^{\circ }}\right)$ and isentropic compressibility$\left(K_{\varphi ,s}^{{}^{\circ }}\right)$ its transfer properties $(\Delta V_{\varphi }^{{}^{\circ }}$, $\Delta K_{\varphi ,s}^{{}^{\circ }})$, expansibility coefficients${\left(\partial E_{\varphi }^{{}^{\circ }}/\partial T\right)}_P$, expansion coefficient ($\alpha$) and interactions coefficients $(V_{AB},K_{AB},V_{ABB},K_{ABB})$ the various interactions among glycols and EDTA in aqueous solution were investigated and addressed. Fourier transform infrared spectroscopy study had also been carried in binary solution.
