Densities of sodium cyclamate (Na-cycl) in water and (0.1, 0.3, and 0.5)m(glucose/sucrose) have been measured at (298.15, 303.15, 308.15, and 313.15) K. From density values, partial molar volumes (V0Φ), expansion coefficient (E∞), Hepler’s constant (δ2V0Φ/δT2)p, apparent specific volumes (ASV), partial molar volumes of transfer (∆trsV0Φ), doublet (VAB) and triplet (VABB) interaction coefficients have been calculated. An increase in the values ofV0Φand ∆trsV0Φwas observed with increase in the concentration of glucose/sucrose. The positive values ofE∞ andV0Φare due to the strong solute-solvent interactions. The positive values of (δ2V0Φ/δT2)psuggest structure making behaviour of sodium cyclamate in water and in presence of glucose and sucrose. The positive values of (∆trsV0Φ) andVABmay be due to the interactions between hydrophilic group (–OH, C=O, and –O–) of glucose/sucrose and sodium ion of sodium cyclamate. All solutions studied exhibit sweet taste because ASV of all solutions ranges from (0.569 × 10-6) m3×kg-1to (0.626 × 10-6) m3×kg-1.

Sugars can affect our blood glucose (sugar), weight and blood fats. Synthetic sugars (artificial sweetener) provide little or no calories or carbohydrate or do not increase blood sugar. In food and pharmaceutical industries, blends of sweeteners are commonly used to design the food products and pharmaceutical doses, the information regarding type and extent of sweetener-sweetener and sweetener -water interactions and taste quality of the solution required. The aqueous solutions of arabinose, xylose and galactose with and without cyclamate are studied. Densities of solutions of arabinose, xylose and galactose in presence of 0.05, 0.15 and 0.3 m sodium cyclamate have been measured at 298.15K. Partial molar volumes, apparent specific volumes, partial molar volumes of transfer and doublet and triplet interaction parameters have been calculated. The information obtained from these parameters has been used to understand type and extent of sweetener-sweetener and sweetener -water interactions and taste quality of the solution.

Effect of different concentrations of aqueous solutions of sodium cyclamate on sugars (mono and disaccharides) are observed by measuring the densities of (sugar + water) and (sugar + water + sodium cyclamate) systems. Densities of aqueous solutions of D (+) mannose (monosaccharide) and D (+) maltose monohydrate (disaccharide) in (0.05, 0.15, 0.3) mol.kg-1 of sodium cyclamate (Na-Cyclamate) at T = 298.15 K have been measured. From experimental values of densities , Vɸ0( partial molar volumes) ΔtrsVɸ0 (partial molar volumes of transfer) ASV (apparent specific volumes) interaction parameters (𝑉𝐴𝐵) and (𝑉𝐴𝐵𝐵 ) have been determined. The calculated values of various parameters have been used to interpret the results in terms of (D (+) mannose – water), (D (+) mannose –water– Na-cyclamate), (D (+) maltose monohydrate – water) and (D (+) maltose monohydrate – water – Na-cyclamate) interactions in sugar– water – Na-cyclamate and quality of taste sense of solutions.

This work reports partial molar volumes, V0, of eight peptides and three other dipolar ions (glycine, diglycine, triglycine, dl-alanyl-dl-valine, glycyl-dl-alanine, glycyl-dl-leucine, glycyl-tyrosine dihydrate, dl-alanyl-glycyl-glycine, l-valyl-glycyl-glycine, l-lysine-l-aspartate, l-lysine-l-glutamate) in water, calculated from density data obtained at 35 °C. V0 data are interpreted in terms of solute–solvent interactions. In some cases where V0 data at 25 °C were available from the literature, a comparison indicates that partial molar volumes of these solutes at 35 °C are higher than their respective volumes at 25 °C by about 2–3 cm3 mol−1. Partial molar expansibilities, E0, were also estimated in such cases. Expansibility data appear to show a trend indicating dependence of E0 values on the chain length of the solute molecules. Some plausible modes of solute–solute interactions are also discussed. Keywords: hydration of dipolar ions, partial molar volumes of peptides, solute–solvent interactions, electrostriction, solute–solute interactions.

In this study we investigated the effects of tetrabutylammonium hydrogen sulphate (Bu4NHSO4) on the solute-solute and solute-solvent interactions in the aqueous solutions of nicotinic acid in terms of apparent molar volumes (?V), standard partial molar volumes (?V0) and viscosity B-coefficients at 298.15, 308.15, and 318.15 K under ambient pressure. These interactions are further discussed in terms of ion-dipolar, hydrophobic- hydrophobic, hydrophilic-hydrophobic group interactions. The activation parameters of viscous flow for Bu4NHSO4 in the aqueous solutions of nicotinic acid were discussed in terms of transition state theory. The overall results indicated that ion-hydrophilic and hydrophilic-hydrophilic group interactions are predominant in the aqueous solutions of nicotinic acid and Bu4NHSO4 has a dehydration effect on the hydrated nicotinic acid.

The paper deals with a correlation of the ternary systems H2O - Na2CO3 - NaHCO3. The corresponding data have been correlated with an equation presuming the additivity of partial molar volumes, the components being water and the so-called basic solutions of Na2CO3 and NaHCO3. From the comparison of experimental and calculated density values of the solutions of Na2CO3 - NaHCO3, Na2CO3, and NaHCO3 at 20 °C it follows that the given procedure provides very precise results.

In this study we investigated the effects of sodium pyruvate on the solution thermodynamics of glycine in terms of the solute-solute and solute-solvent interactions in aqueous solutions. Measured density and viscosity were used to derive apparent molar volumes (?V), standard partial molar volumes (?V0) and viscosity B-coefficients at 298.15, 303.15 K, 308.15, and 318.15 K under ambient pressure. The interactions are further discussed in terms of ion-dipolar, hydrophobic- hydrophobic, hydrophilic-hydrophobic group interactions. The activation parameters of viscous flow were also discussed in terms of transition state theory. The overall results indicated that ion-hydrophilic and hydrophilic-hydrophilic group interactions are predominant in the ternary solutions.

Partial molar volumes of ammonium aluminium sulfate and potassium aluminium sulfate in DMF-water mixtures (5-20 wt.% of DMF) have been determined from solution density measurements at various temperatures and electrolyte concentrations. The data were evaluated by using Masson equation and the obtained parameters were interpreted in terms of ion-solvent and ion-ion interactions. Both electrolytes have been found to act as the structure makers/promotors in DMF-water systems.

The solubility, partial molar volume and standard integral molar enthalpy of solution of cis- and trans-[CoCl2(en)2]Cl in water, aqueous methanol, aqueous tert-butyl alcohol and aqueous acetonitrile are reported. The transfer functions ∆Gt0, ∆Ht0 and T∆St0 as well as partial molar volumes are used to obtain information on the solute-solvent interactions. Results obtained are discussed in terms of differences in the surface charge distribution in isomeric coordination species.
