model,2’ A,G” is a function of the ionic charge and radius and of the solvent permittivity. It is therefore not surprising that the three anions, NOT, 03’-, and SO2’-, have Gibbs solvation energies that are rather similar, and the extrapolation to C02*-seems justified. The major source of error in our estimate lies in the uncertainty of the electron affinity. The values of A,Go given above are relative to A,+Go(H+) = 0. Absolute Gibbs hydration energies are 03*-, -3 18 kJ/mol; NO
