Thermo Acoustical Analysis of Multicharged Electrolytes In Mixed Solvents At Varying Temperatures

Abstract

ABSTRACT newlineUltrasonic is an interesting field of study which makes an effective contribution to many areas of human endeavour. In recent years many attempts have been made in the field of ultrasound in solids, liquids and gases. The study of propagation of ultrasonic waves in liquid systems and solids is now well established as an effective means of examining certain physical properties of the materials. It is particularly well adapted to examining changes in such physical properties at the macro level. The data obtained from ultrasonic propagation parameters in liquid mixtures and solutions that are ultrasonic velocity and attenuation and their variation with concentration of one or more of the components, helps to understand the nature of molecular interactions in the mixtures. Ultrasonic wave propagation affects the physical properties of a medium, hence such studies in pure liquids and in binary and ternary mixtures of electrolytes and non-electrolytes enables one to calculate thermodynamic parameters and their excess values which are of great use in understanding the nature and strength of molecular interactions. newlinePhysico-chemical studies of electrolytes based on determination of partial molar properties, viscosity, conductance and thermo-acoustic parameters have gained paramount importance for studying ion-ion, ion-solvent interactions in aqueous, non-aqueous and mixed solvent media. Water, the unique solvent plays a crucial role in studying physico-chemical aspects of most of the reactions. Physical measurements of aqueous and non-aqueous electrolytic solutions takes into account of structure making or structure breaking properties of ions in such solvents. Recent developments reveal the significance of ultrasonic velocity in pharmaceutical fields, industry and engineering. newlineIn view of the above facts, certain multicharged electrolytes like Sodium chromate, Potassium chromate, and Sodium thiosulphate are selected for investigation. The aim of this research work is to determine accurate data on thermodynamic an
