Abstract: • Volumetric, acoustic and viscometric properties of amino acids in aqueous thiamine-HCl solutions were determined. • Apparent molar volume and transfer volume were calculated and analyzed. • Hepler's constant and d B /d T suggests structure making behavior of both the amino acids in aqueous thiamine-HCl solution. • The nature of solute-solute and solute-solvent interactions has been probed. The volumetric, acoustic and viscometric properties are used for investigating the interactions of l -serine and l -arginine in aqueous solutions of a vitamin, namely, thiamine hydrochloride, over a temperature range of (293.15–313.15) K and at atmospheric pressure. The limiting apparent molar volume, V 0 ϕ , and empirical parameter, S v , is evaluated from apparent molar volume, V ϕ. Similarly, limiting apparent molar isentropic compression, K 0 ϕ,s , and slope, S k , is evaluated from apparent molar isentropic compression, K ϕ,s. The corresponding transfer properties (Δ tr V 0 ϕ and Δ tr K 0 ϕ,s) from water to aqueous vitamin solutions are also evaluated. The viscosity data has also been used to analyze relative viscosity, ƞ r , viscosity B -coefficients and temperature derivative of B -coefficients, dB / dT. The various calculated parameters assist to procure valuable information regarding the presence of different kinds of intermolecular interactions in the ternary (l -serine/ l -arginine + water + thiamine-HCl) solutions.
