Ultrasonic and Density Studies of D(+) Mannose with Aqueous Electrolytes at 303K
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 , MgCl2and CaCl2at 303 K. Experimental values of densities and ultrasonic velocities were carried out of the ternary mixture solution D(+) mannose with aqueous NaCl ,KCl, MgCl2and CaCl2. Aqueous alkali metal halides (NaCl ,KCl , MgCl2and CaCl2) were added under different molalities with D(+) mannose. The related and relevant parameters correlated to the present study such as adiabatic compressibility Ks, acoustic impedance Z, apparent molal volume фv, apparent molal adiabatic compressibility, фKs, and partial molal volume ф0vand partial molal adiabatic compressibility, фoKsat 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.
