Densities of sodium arsenite (NaAsO2) aqueous solution with the molality varied from 0.19570 to 1.94236 mol·kg−1 at temperature intervals of 5 K from 283.15 to 363.15 K and 101 ± 5 kPa were measured by a precise Anton Paar Digital vibrating-tube densimeter. Apparent molar volumes (VΦ) and thermal expansion coefficient (α) were obtained on the basis of experimental data. The 3D diagram of apparent molar volume against temperature and molality and the diagram of thermal expansion coefficient against molality were generated.

Abstract:

The densities of 1,3-butanediol-water mixtures and some tetraalkylammonium iodide salt solutions in these solvent mixtures at different concentrations (0.02 M-0.14 M) have been determined at 298.15 K using magnetic float densitometer technique. Then apparent molar volumes ΦVof the electrolytes in above solvent mixtures were calculated. The apparent molar volumes of transfer ∆ΦV° (tr) were also calculated and the ion-ion / ion- solvent interactions are then discussed on the basis of changes in the Masson's slope and apparent molar volumes of transfer data.

This paper studies volumetric properties of ternary dimethylsulfone-ethanol-water systems. The biomedical and environmental significance for the fundamental investigations of aqueous solution of dimethylsulfone and influences of third component on volumetric behavior of this system arises from several reasons. In the global sulfur cycle dimethylsulfide is converted to dimethylsulfone leading to an annual atmospheric production of some million tones of dimethylsulfone, much of which would be deposited in rain and snow. In addition, dimethylsulfone has been extensively studied from a medical poi

We have studied the composition dependence of density of liquid water-DMSO mixtures at different temperatures by using the isobaric-isothermal (NPT) molecular dynamics computer simulations. The non-polarizable semi-flexible, P1 and P2 models for the DMSO molecule combined with the TIP4P-2005 water model are considered. The excess mixing volume and the apparent molar volumes of the species are reported. We have established that the P1-TIP4P-2005 model for the mixture provides a very good description of the location of the minimum of apparent molar volume for DMSO species indicating the anomaly.
