Abstract

The pK1 * and pK2 * of H2SO3 have been determined in NaCl solutions as a function of ionic strength (0.1 to 6 m) and temperature (5 and 25 °C). The extrapolated values in water were found to be in good agreement with literature data. The experimental results have been used to determine the Pitzer interaction parameters for SO2, HSO3 -and SO3 -in NaCl solutions. The resultant parameters for NaHSO3 and Na2SO3 were found to be in reasonable agreement with the values for NaHSO4 and Na2SO4. It, thus, seems reasonable to assume that the interactions of Mg2+ and Ca2+ with HSO3 -and SO3 -can be estimated from the values with HSO4 -and SO4 -until experimental values are available. Measurements of pK1 * and pK2 * in artificial seawater were found to be in good agreement with the calculated values using the derived Pitzer parameters. It is, thus, possible to make reasonable estimates of the activity coefficients of HSO3 -and SO3 -ions and pK1 * and pK2 * for the ionization of H2SO3 in marine aerosols.
