IONIC EQUILIBRIA IN MIXED SOLVENTS. IX. THE AUTOPROTOLYSIS CONSTANTS OF MIXTURES OF WATER AND AN AMPHIPROTIC SOLVENT
A thermodynamic consideration is made for the autoprotolysis constant of a mixture of water and an amphiprotic solvent on the basis of equilibria of hydronium-lyonium and hydroxyl-lyate ions. The autoprotolysis constants of various water-methanol solutions are calculated and compared with those in literature. The calculated values of autoprotolysis constants of water-ethanol and water-n-propanol solutions are presented.
