摘要：

The acidity functions of aqueous trifluoroacetic and trifluoromethanesulphonic acid mixtures, and aqueous hexafluoropropane-2, 2-diol solutions, have been determined by differential pulse polarography. The apparent shift of the half-wave potential for the ferrocene-ferricinium couple, as the solvent composition is changed, is used to indicate the change in potential of a glass electrode; acidity is measured as the HGF acidity function. The densities of two of these solvent systems as a function of composition are also reported. Trifluoromethanesulphonic acid-water mixtures represent the strongest aqueous acid solvent system so far studied. © 1979.
