Abstract

In the present study, the solvent-solute, solvent-ion, solvent-solute (L) and solute (ion) and solute (L)-solute (ion) interactions were investigated by ultrasonic velocity and density measurements at 301K at 0.01 molar concentration in 70% dioxane-water as solvent. The main goal of this study was to find the effects of nuclear charge, ionic size, ionic ratio, ionization potential, tendency of metal ions to form π bond etc. of different metal ions with ligand [L=l-H-3-(2-hydroxy-3,4-benzophenyl)-5-phenyl-2-pyrazoline in solute-solute interaction and also on solvent in solvent-solute interaction and to note the changes in the acoustic properties like β_s, Φ_v, L_f, R_A, and Z. This study explores the effects of various metal ions in solute (L)~solvent (ion) interaction and solvent-solute interaction.

Abstract

Ultrasonic velocity and density measurement of 2-hydroxy-3-substituted-5-methyl-bromoqcetophenones and 2-(4'-H/chloro)benzylidene-5-methyl-7-substituted coumaran-3-ones were carried out in ethanol and dioxane respectively for solute-solvent, solute-solute interactions. These interactions were also performed with Cu(II) and Fe(III) metal ions at 303.15 K. The data obtained during the study is used for determining the most significant acoustic parameters like apparent molar compressibility (Φ_K) and specific acoustic impedance (Z). These parameters explore solute-solute and solute-solvent interactions in different solvents. In this investigation, the comparative study of effect of solvents, effect of metal ions and effect of substituents in the solute are studied on molecular interaction of the matter.
