Present study deals about the experimental results of ultrasonic velocity, density and viscosity along with estimated
parameters for the liquid mixture of magnesium salicylate tetrahydrate (MST) as solute and 50% ethanol as a solvent at
298.15K, 303.15K and 308.15K temperatures. The frequency selected for measurements of velocity is 4MHz. The measured
values of density (ρ), ultrasonic velocity (v) and viscosity (η) are used to calculated various thermoacoustic parameters like
Adiabatic compressibility (βs), free length (Lf)
