Ultrasonic is the universally accepted technique to study the physico-chemical properties of the liquids, liquid mixtures, electrolytic solutions and polymeric solutions. Liquids, liquid-mixtures and solutions find wide applications in medical, pharmaceutical, chemical, lather, textile, nuclear and solvent, solution related industries. The study and understanding of the thermodynamic properties of liquid mixtures and solutions are more essential for their applications in these industries. The measurements of ultrasonic velocity in the combination of density and viscosity have been used to study the molecular interactions in liquid mixtures and solutions.

Ultrasonic:
Ultrasonic is science of acoustics dealing with generation and use of inaudible acoustic waves. The sound waves having frequencies ranging above 20KHZ up to several MHZ i.e. human audible ranges are called ultrasonic waves. The sound waves of low frequencies i.e. below human audible range are infrasonic waves. Like life, ultrasonic was originated from sea. The five senses of living beings i.e. hearing, touch, smell, sight and taste are interdependent on each other. Out of these five, two are important for long rang interaction i.e. sight and hearing and other three have short range performance. But these things are different under water because long range sight has no use under water. By default, sound waves have long range sensing functionality under water.
The era of ultrasonic began with the wrecking of RMS Titanic which crashed with ice berg. The detection of ice berg was done by high frequency waves. In 1915 Langevin (the father of ultrasonic) invented the underwater SONAR for submarine detection. Sokolov suggested the concept of ultrasonic metal flaw detection in 1928. After that slow and steady progress was made in the measurement of propagation constant of material. The propagation of ultrasonic waves through solid material has been used to detect hidden cracks, porosity, voids and other discontinuities in metal. The field of ultrasonic has wide application in science, medicine and
