Molecular conductancem, relative viscosity and density of oxalic acid at different concentration in dilute aqueous solution were measured at 293 K. The conductance data were used to calculate the value association constant. Viscosity and density data were used to calculate the A and B coefficient of Jone-Dole equation and apparent molar volume resp...

... Theoretically, A and B stand for viscosity parameters that describe solutesolvent and solute-solute interaction in diverse systems. A role of viscosity has gained the attention of several studies in characterizing the molecular interactions in aqueous and nonaqueous solution during the past decade [4][5][6][7][8][9][10][11] . Alcohols are biologically and technologically significant amphiphilic materials that are in the liquid state as a result of hydrogen bonding of their O-H groups. ...

Viscosity (η) of solutions of 1-butanol, sec-butanol, isobutanol and tert-butanol were investigated in aqueous solution structures of ranged composition from 0.55 to 1 mol.dm-3 at 298.15 K. The data of (η/η˳) were evaluated based on reduced Jone-Dole equation; η/η˳ =BC+1. In the term of B value, the consequences based on solute-solvent interaction in aqueous solutions of alcohols were deliberated. The outcomes of this paper discloses that alcohols act as structure producers in the water. Additionally, it has shown that solute-solvent with interacting activity of identical magnitude is in water-alcohol system.

The aim of this study is to develop the methodology to get the pH values of the palaeo-circulation in the system H2O-CO2-HCO3--NaCl in the P-T conditions of circulation. It combines the use of an experimental approach for calibrating the analytical method, Raman spectrometry, and numerical modelling for the quantitative interpretation of phase and chemical species equilibria. The routine analytical techniques for fluid inclusions are used to carry out the experimental analyses, such as microthermometry and micro-Raman spectroscopy. Experiments are based both on the use of synthetic fluid inclusions produced in quartz crystal and a new method to make synthetic fluids in fused-silica glass capillary. The synthetic fluid in silica glass capillary can be applied to a wide range of pressure (up to 2 to 3 kbar) at room temperature and temperature (as high as at least 673 K). The experimental protocol of capillary loading with different chemical species in the system H2O-CO2-HCO3--NaCl and the methods to quantify their amount are elaborated and validated. Numerical modelling is based on the use of the Pitzer model to describe the liquid aqueous phase, especially the activity coefficients of each chemical species in the liquid aqueous phase. The Duan equation of state is used for the P-V-T-X properties of the liquid and vapour phases in the simplified subsystem H2O-CO2-NaCl. The application pressure and temperature ranges of the model are respectively 273 to 523 K, and 0 to 2000 bar. Range of NaCl concentration is between 0 and 5 molal and corresponds to the range of ice melting temperature (Tmice). The determination of the concentration of aqueous species HCO3- and CO2 is performed by using micro-Raman spectrometry and is calibrated with using the standards of synthetic fluid inclusion and silica glass capillary. A software program based on the Pitzer and Duan models has been done for the interpretation of i) ice melting temperature (Tmice) and bicarbonate concentration in terms of NaCl concentration, and ii) total homogenisation temperature in terms of bulk molar volume and pressure at homogenisation temperature. Then speciation of the fluid is calculated along the isochore till the trapping temperature if lower than 250 °C. A first application to the Mokrsko gold deposit in Bohemian Massif is done and discussed

Uranyl ion, UO 2 ²⁺ , and its aqueous complexes with organic and inorganic ligands can be the dominant species for uranium transport on the Earth surface or in a nuclear waste disposal system if an oxidizing condition is present. As an important biodegradation product, oxalate, C 2 O 4 ²⁻ , is ubiquitous in natural environments and is known for its ability to complex with the uranyl ion. Oxalate can also form solid phases with uranyl ion in certain environments thus limiting uranium migration. Therefore, the determination of stability constants for aqueous and solid uranyl oxalate complexes is important not only to the understanding of uranium mobility in natural environments, but also to the performance assessment of nuclear waste disposal. Here we developed a thermodynamic model for the UO 2 ²⁺ –Na ⁺ –H ⁺ –Cl – –ClO 4 – –C 2 O 4 2– –NO 3 – –H 2 O system to ionic strength up to ∼11 mol•kg ⁻¹ . We constrained the stability constants for UO 2 C 2 O 4 (aq) and UO 2 (C 2 O 4 ) 2 ²⁻ at infinite dilution based on our evaluation of the literature data over a wide range of ionic strengths up to ∼11 mol•kg ⁻¹ . We also obtained the solubility constants at infinite dilution for solid uranyl oxalates, UO 2 C 2 O 4 •3H 2 O, based on the solubility data over a wide range of ionic strengths. The developed model will enable for the accurate stability assessment of oxalate complexes affecting uranium mobility under a wide range of conditions including those in deep geological repositories.

In the present study, the effect of concentration and temperature on the viscosities of aqueous solution of perchloric acid is discussed. The experiments were done at 283.65 and 297.65 K. The three concentration regions in perchloric acid-water system have been identified from Jones-Dole viscosity equation and the positive value of B-coefficient indicates strong ion-solvent interaction or water structure making character. The effect of temperature on viscosity B-coefficient confirms that perchloric acid have water structure making character.

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 ΦV of 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.
