The ultrasonic velocity of vanadium laurate confirms that there is a significant interaction between the solute-solvent molecules in dilute solution and the carboxylate molecules do not aggregate appreciable in dilute solutions. The value of Critical Micelle Concentration (C.M.C.) for vanadium laurate is in agreement with those obtained from other physical parameters. The effects of concentration and chain length of soap on ultrasonic velocity and the various acoustic parameters (Adiabatic compressibility, specific acoustic impedance, intermolecular free length, apparent molar compressibility, apparent volume, molar sound velocity, molar sound compressibility, Relative association and relative association solvation ) have been investigated.
