ThBr4 Thorium bromide

In his early study covering a large number of halides and oxyhalides of thorium and their hydrates, Chauvenet [1911CHA] reported a value of -293.67 kJ moT for the enthalpy of solution of ThBr4(cr) in ca. 16000 H2O, probably at 288 K. Use, as discussed in Appendix A, of the values adopted by this review (Table VII-15) for the hydrolysis of the thorium ion and of that for the formation of the first thorium bromide complex (Section VIII.2.2) leads to a dissolution reaction that can be written as ...
