Ultrasonic and Density Studies of D(+) Mannose with Aqueous Electrolytes at 303K

Abstract:

The present experimental investigation was carried out in order to explore the possible molecular interactions of D(+) mannose with mixed solvent of aqueous NaCl, KCl , MgCl₂ and CaCl₂at 303 K. Experimental values of densities and ultrasonic velocities were carried out of the ternary mixture solution D(+) mannose with aqueous NaCl ,KCl, MgCl₂ and CaCl₂. Aqueous alkali metal halides (NaCl ,KCl , MgCl₂ and CaCl₂ ) were added under different molalities with D(+) mannose. The related and relevant parameters correlated to the present study such as adiabatic compressibility K_s, acoustic impedance Z, apparent molal volume ф_v, apparent molal adiabatic compressibility, ф_Ks, and partial molal volume ф⁰_v and partial molal adiabatic compressibility, ф^o_Ks at infinite dilution. The present investigation has exploited the possible molecular associations such as ion-ion, ion-solvent, solute-solute and solute-solvent interactions in these systems. It has been observed that there exist strong solute-solvent interaction and complex formation between in these ternary systems.
