Acidity in aqueous mixed solvent systems—III : Influence of the organic solvent molecular structure on the acidity of aquo-organic mixtures (acidity function, water structure, hydrophilic and hydrophobic effects)

The acidity functions Ho and H R have been determined for different aqueous organic mixtures (diols, carbohydrates) at constant acid concentration. We have checked, with a reaction involving a slow proton transfer, that Ho and H R vary in direct proportion to the acidity of the systems. The results...

Description
Summary:The acidity functions Ho and H R have been determined for different aqueous organic mixtures (diols, carbohydrates) at constant acid concentration. We have checked, with a reaction involving a slow proton transfer, that Ho and H R vary in direct proportion to the acidity of the systems. The results are interpreted in terms of the variations of the proton activity which is dependent on the modifications of the water structure by the organic cosolvent.
