The acoustical properties 1-Carboxamido-3-(2-hydroxy-5-methylethylphenyl)-5-phenylpyrazole have been investigated at different concentration in 70% dioxane-water and acetone-water mixture. Different acoustic/thermodynamic parameters such as adiabatic compressibility (bs), apparent molar adiabatic compressibility (Fk), apparent molar volume (Fv), intermolecular free length (Lf) specific acoustic impedence (Z), and relative associaiton (RA) have been calculated using ultrasonic velocity (U) and density (d) values at 34.5°C.
