Abstract
Ultrasonic velocity and density measurements of tetra hydrated manganous chloride in aqueous media have been made at 303.15, 308.15, 313.15 and 318.15K to investigate ion-solvent interactions. The gradual increase of ultrasonic velocity (U), density (ρ and acoustic impedance (Z) and gradual decrease of adiabatic compressibility (β), intermolecular free length (Lf) suggested the presence of strong ion-solvent interactions. Mn+2 ions possess structure making tendency for the cluster of water molecules. The solvation number (Sn) shows non linear variation with temperature and gradual decrease with concentration also confirms strong interactions between Mn+2 ions and dipolar water molecules
