Ultrasonic Studies of Some Biomolecules in Aqueous Guanidine Hydrochloride Solutions at 298.15 K

Abstract

Ultrasonic velocity (U), viscocity (η) and density (ρ) of L -ascorbic acid, dextrose and sucrose in aqueous guanidine hydrochloride (0.3 m) have been measured at 298.15 K. The derived acoustical parameters namely adiabatic compressibility (β), apparent molal compressibility (ϕ K ) apparent molal volume (ϕ v ) limiting apparent molal compressibility ((ϕ 0 K ) limiting apparent molal volume (ϕ 0 v ) and their constants (S K, S V ) and viscosity Bcoefficient and hydration number (n H ) have been computed from the experimental data. The variation of these parameters with respect to the molality of solutes have been explained on the basis of solute-solvent interaction and structure making tendency of the solutes in solvents.

Analysis of thermo-acoustic parameters in view to obtain the interaction between acetamide in some salt solutions at different temperature

“…NaCl helps restore the human body due to certain conditions and controls blood pressure. This investigation involves the determination of volumetric and acoustical properties for interaction between acetamide and two different electrolyte salt solutions NaCl, and KCl at various concentrations and temperatures [9]. From this data, we calculate some allied parameters and from this, we can find the intermolecular interaction between them.…”
