Lutetium selenites

Smolyakova and Serebrennikov [78SMO/SER] measured the enthalpy change of the reaction between an aqueous solution of lutetium chloride and Na2Se03(cr). The description of the experiments and calculations is somewhat meagre. Their data have been re-evaluated as described in Appendix A and yielded the result Af(Lu2(Se03)3-8H20, am, 298.15 K) = - (5176 + 12) kJ mol .  

As an amorphous phase is apparently formed when lutetium selenite is precipitated from aqueous solution, the result of this investigation is included in the review but not selected. 

No other thermodynamic data have been found for lutetium selenites.
