Abstract
The first thermodynamic dissociation constants of glycine in 5, 15 mass % glucose+water mixed solvents at five temperatures from 5 to 45°C have been determined from precise emf measrements of a cell without liquid junction using hydrogen and Ag-AgCl electrodes and a new method of polynomial approximation proposed on the basis of Pitzer's electrolytic solution theory in our previous paper. The results obtained from both methods agree within experimental error. The standard free energy of transfer for HCl from water to aqueous mixed solvent have been calculated and the results are discussed.
