| Abstract: | Single ion activities in aqueous H2SO4 have been calculated from the mean ionic activity coefficients of H2SO4, the solubilities of PbSO4 and the degrees of the second dissociation of H2SO4 in these solutions by employing a new extra-thermodynamic assumption. The hydrogen ion activities thus obtained are compared with the corresponding acidity function values based on different classes of acid-base indicators. |
