(INDIA) <p>&nbsp;</p> <p style="text-align: justify;">Ultrasonic velocities and ultrasonic densities of 3 (2&#39;- aminophenyl)- 4-pyridoyl - 5 (2- hydroxyl phenyl) pyrazoles, in <strong>70% </strong>acetone-water have been evaluated at 308.15 K by using interferometer at a frequency of 2.0 MHz. The ultrasonic velocity, density and concentration were used to calculate, partial molal volume (^v) apparent molar compressibility, intermolecular free length (Lf), Adiabatic compressibility <em>(fis)</em> Specific acoustic impedance (Z) and Relative association (R<sub>A</sub>) to throw the light on the solute-solute interaction <strong>and </strong>solute-solvent interaction.</p> <p>&nbsp;</p> <p>&nbsp;</p> https://journalofchemistry.org/paper/867/ Acoustical properties Substituted pyrazole acetone-water mixture
