Exploring ultrasonic wave transmission in liquids and liquid mixtures: A comprehensive overview.

• This review paper focuses on the ultrasonic studies to investigate the molecular structure and interactions in various liquid mixtures, including binary, ternary, and organic solutions. • The ultrasonic study has gained popularity due to its non-destructive testing (NDT) nature and finds applications in medical and scientific fields, agriculture, industries, and more. • The primary objective of this review is to explore the interactions between different liquid mixtures, employing different evaluation criteria. • Thermo properties, excess functions, and acoustic parameters are essential components of the examined research papers. An understanding of the molecular process can be gained by analyzing the molecule interaction using the knowledge of how thermodynamic parameters vary with composition and temperature. Reliable information about the chemical and physical characteristics of a broad range of liquid mixes is required by industry. This review examines multiple research papers investigating molecular interactions, focusing on the acoustic/ultrasonic technique. This technique employs ultrasonic waves to probe molecular interactions. Researchers utilized an ultrasonic interferometer to measure ultrasonic wave velocity, liquid density can be determined by using a specific gravity bottle, and employed the Ostwald viscometer for viscosity measurements. The velocity of ultrasonic waves, the density of a particular liquid combination, and viscosity can all be measured to analyze various acoustic and thermodynamic properties. Understanding the molecular interactions in each sample is greatly aided by this study. A detailed explanation of the many measured parameters has been provided. [ABSTRACT FROM AUTHOR]
