Acoustical study of aqueous manganese chloride solutions at varying temperatures by ultrasonic technique
Abstract
Ultrasonic velocities, densities and viscosities in very dilute concentrations of aqueous MnCl2.4H2O system have been determined at 303.15K, 308.15K, 313.15K and 318.15K temperatures. Using this data, the acoustical parameters such as adiabatic compressibility’s (β), intermolecular free lengths (Lf), specific acoustic impedances (Z) and solvation numbers (Sn) have been estimated. The results have been interpreted in light of ion-solvent interactions in terms of structure breaking and structure promoting nature of Mn+2 ions in aqueous media.
