An Examination of the Transport and Acoustics Properties of B3 Vitamins and Aqueous MgCl2 Salt at Various Temperatures and Concentrations

Abstract

Forecasting various forms of intermolecular contact and the degree to which the solute and solvent are bonded is highly advantageous when using thermo-acoustical and volumetric data. Both salts and vitamins are abundant in the human body. A variety of thermo-acoustical and volumetric properties (viz. velocity [U], density [ρ], adiabatic compressibility [β], surface tension [σ], specific heat ratio [γ], acoustic impedance [Z], relative association [R_A], relaxation strength [r], isothermal compressibility [kT], and nonlinearity parameter [B/A]) are investigated in this study. Of the vitamin B₃ + H₂O and vitamin B₃ + H₂O + MgCl₂ systems have been examined. Through solvation and hydrogen bonding, these characteristics are utilized to describe the interactions between solutes and solvents. Compressibility explains the qualitative intermolecular elastic forces that exist between the molecules of the solvent and the solute. The electrostatic field of ions has formed the basis for discussions on the structural arrangement of molecules in electrolyte solutions. The volumetric and thermoacoustic characteristics exhibit concentration-dependent changes, suggesting the existence of molecular interactions in both systems. The vitamin B₃ molecule shows stronger molecular contact at higher solvent concentrations, although it interacts most molecularly with MgCl₂ solvents. This suggests that magnesium molecules are more suited for the attachment of vitamin B₃ molecules than are water molecules.
