Abstract
Solvation Study of Neem Oil in Aqueous Sodium Dodecyl Sulphate at different Temperatures
Highlights
The study of propagation of ultrasonic waves in liquid system is well established as an effective means for examining certain physical properties of the materials [1]
The values of adiabatic compressibility (β), molal hydration number, apparent molal compressibility ( k), apparent molal volume ( v), the limiting apparent molal compressibility ( k0), limiting apparent molal volume ( v0) and their constants, A and B co-efficients of Jones-Dole equation are shown in table 2-5
The density values increases with neem oil concentration but it decreases with rise in temperature
Summary
The study of propagation of ultrasonic waves in liquid system is well established as an effective means for examining certain physical properties of the materials [1]. At a particular concentration, surfactant molecules get associated to form aggregates or micelles [7,8,9]. The ultrasonic velocity data alone will not provide sufficient information about nature and types of interactions present in the solution. Their derived parameters such as adiabatic compressibility (β), molal hydration number (nh′), apparent molal compressibility ( k), apparent molal volume ( v), limiting apparent molal compressibility ( k0), limiting apparent molal volume ( v0) and their constants (Sk, Sv) and viscosity B co-efficient have been found to know about the various types of interactions exist between solute and solvent. The accuracy of the measurement of temperature was + 0.1° C
