Ultrasonic velocities and densities have been measured for the aqueous solution of manganese sulphate, nickel sulphate and copper sulphate in polyvinyl alcohol solution, in different concentration at 303K. Adiabatic compressibility, intermolecular free length, acoustic impedance, surface tension and other acoustical parameters have been calculated to assess the polymer-ion interaction. It is seen that the ultrasonic velocity increases initially with the increase in the concentration of manganese sulphate, nickel sulphate and copper sulphate salts in polyvinyl alcohol solution. The increase in velocity with concentrations suggests the increase in cohesive forces due to polymer-solvent interactions. The ion-solvent interaction is relatively weak in the case of polyvinyl alcohol solution containing Mn+2 and copper ions. Further study may give more details about complex ion formation.
