Abstract
The dissociation of hydronium trifluoromethanesulfonate (H 3 OSO 3 CF 3 ), hydronium perchlorate (H 3 OClO 4 ) and anhydrous perchloric acid has been investigated using conductimetry in propylene carbonate. HClO 4 ( K A =10 −1.3 mol l −1 ) and H 3 OSO 3 CF 3 ( K D =10 −1.7 mol l −1 ) are not completely dissociated; H 3 OClO 4 is found to behave as a strong electrolyte in the solvent. The determination of the conditional potential of H + /H 2 couple ( E′ H 2 0 ), has been achieved using the hydrogen electrode in solutions of perchloric and trifluoromethane-sulfonic acids. Potentiometric titrations of molecular and anionic bases with HSO 3 CF 3 , with hydrogen or glass electrodes, yield the p K A values of the acid-base couples used; in the case of HA acids (sulfuric, nitric, acetic, picric and hydrogen chloride) homoconjugation equilibria have been investigated. The acidity scale so obtained in propylene carbonate is correlated with the water one using the transfer coefficient of the proton between the two solvents.
