Hydrated solid thorium sulphates

As discussed in Appendix A, the water vapour pressure data give a very different value of Aj//° ((1X.17), 298.15 K) = -(102.5 + 28.4) kJ-mok , again ignoring the small temperature difference from 298.15 K. The large uncertainty is due to a 

The value selected by this review is that from the calorimetric study  

A large number of hydrated thorium sulphates have been reported in the literature [1910KOP/HOL], [1910BAR], [1911BAR], [1912BAR], 

Th(S04)2 4H20, and a variety of hydrated double salts such as Th(S04)2-Na2S04-6H20, Th(S04)2-K2S04-4H20, Th(S04)2-2K2S04-2H20,
