The ultrasonic velocity density and viscosity of binary liquid mixture of tetrahydrofuran and strontium hydroxide (solvent) have been measured over the entire range of compositions at the temperatures 298K, 303K, 308K at fixed and frequency 7 MHz. The observed basic experimental data have been utilized to evaluate some of the derived thermoacoustic parameters such as adiabatic compressibility, molar volume relaxation time. The behavior of these derived parameters and their excess values of, adiabatic compressibility, molar volume relaxation time were evaluated with composition of the mixture and have been discussed in terms of nature and strength of molecular interactions between the constituents. Broad classification study also helps to understand the molecular interaction types.
