Formation constants of thorium sulphate complexes

The calculation of log,o from the data given in Table IX-1 and Table IX-2 for the reaction  

Th(S04)2(aq) were obtained by combining the average values of log,o and log,o with the logj(, = 1.98 for the protonation of sulphate, SOj +lT HSO4 (Table IV-2). f This logjd/ 3° value is based on reinterpretation of experimental data of [1963ALL/MCD] using the 

No value recommended for this reaction, see text for details. 

It is assumed that the values reported in Appendix B for Th and H with CIO4 apply to the corresponding HSO4 interaction.
