Vidhya Sagar and Meera Sharma

The ultrasonic velocity of thorium soaps has been measured in benzene-methanol mixture (50-50%) at a constant temperature (40±0.05°C). The ultrasonic velocity and density data have been used to evaluate the adiabatic compressibility, intermolecular free length, molar sound velocity, specific acoustic impedance and other acoustic parameters. Thorium soap solutions obey Bachem's relation. The results confirm that thorium soaps act as weak electrolyte in dilute solution below the CMC. The values of CMC are in agreement with the values obtained from other properties.
