| Abstract: | Standard potentials (Emo) of the Ag-AgCl electrode in alanine aqueous solutions and in valine aqueous solutions at 298. 15,303. 15,308.15,313.15 and 318. 15K have been determined from the emf measurements of cells of the hype:Pt, H2 (g,p)|HCl(m)+amino acid+H2O|AgCl-Ag These Values have been utilized to evaluate the transfer quantities (△Gto,△Hto,△Sto)accompanying the transfer of 1 mole HCl from water to the amino acid+water mixtures.Attempts have been made to explain the variations of the transfer quantities with the composition of the studied amino acid aqueous solutions in the light of ionsolvent interactions and the structural effects of the solvents |
