The ultrasonic velocity (U) density (ρ) and viscosity (η) of binary liquid mixture of Ammonium Hydroxide with ethanol have been measured over the entire range of compositions at the temperature 313K and frequency 1MHz. The observed basic experimental data have been utilized to evaluate some of the derived thermo acoustic parameters such as free volume, internal pressure, relaxation time and Gibbs free energy. The behavior of these parameters and the excess values of free volume, Internal pressure, relaxation time, and Gibbs free energy were evaluated with composition of the mixture and have been discussed in terms of nature and strength of molecular interactions between the constituents.

The ultrasonic velocity (U) density (ρ) and viscosity (η) of binary liquid mixture of Ammonium Hydroxide with ethanol have been measured over the entire range of compositions at the temperature 313K and frequency 1MHz. The observed basic experimental data have been utilized to evaluate some of the derived thermo acoustic parameters such as free volume, internal pressure, relaxation time and Gibbs free energy. The behavior of these parameters and the excess values of free volume, Internal pressure, relaxation time, and Gibbs free energy were evaluated with composition of the mixture and have been discussed in terms of nature and strength of molecular interactions between the constituents.
