Volumetric and Viscometric Studies of Solute –Solvent and Solute-Solute Interactions of Glycine in Aqueous in Aqueous Electrolytes at 30oC

Densities and viscosities of Glycine in aqueous NaCl and MgCl2(0.02& 0.06 M ) solutions have been determined experimentally at 30oC.The results obtained from density and viscosity measurement have been used to calculate A and B coefficients and free energies of activation of viscous flow of solvent Δ µ10# and solute Δ µ20# .The results are discussed in terms of the dehydration effect of the electrolytes upon the amino acids and weak solute- solute and strong solute- solvent interactions. The properties of these amino acids in water and water+ electrolytes solution systems are discussed in terms of the charge , size and hydrogen bonding effect.
