| Abstract: | Ultrasonic velocities(u) and densities(ρ) of aqueous
and dimethyl sulphoxide(DMSO) solutions of manganous(II) sulphate cobalt(II)
chloride, nickel(II) sulphate, ferrous sulphate, copper(II) sulphate, zinc(II)
sulphate, lanthanum(III) nitrate, cerium(IV) nitrate, uranyl nitrate and thorium(IV)
nitrate in a wide range of concentrations at a temperature 303K have been
measured. Acoustical parameters, such as, adiabatic compressibility ( ), free length (Lf) and solvation
number(Sn) are computed to assess the ion-solvent interaction
in these solutions . It is found that the ion-solvent interactions depend on
concentration, ionic size and nature of metal ion. The transition and inner
transition metal ions behave as structure breaker for the associated clusters
of water molecules, especially in dilute solution, as evidenced from the trend
in the solvation number with molarity. It is also found that the strength of
ion-dipole interaction in aqueous solution of the metal ion is also dependent
on concentration. |
