Abstract

The heats of solution of Yttrium, YOCL, YOBr, YOI, YCl3, YBr3, YI3 and Y2O3 were determined in 4n HX. From those the enthalpies of formation of Yttrium Trihalides YX3 and Yttrium Oxyhalides YOX at 298 K were derived:

ΔHB0(YCl3,f,298) = -240.4 ± 0.6 kcal/mol, ΔHB0(YBr3,f,298) = -202.1 ± 1.5 kcal/mol,

ΔHB0(YI3,f ,298) = -147.0 ± 1.7 kcal/mol, ΔHB0(YOClf,298) = -240.2 ± 1.0 kcal/mol,

ΔHB0(YOBrf,298) = -229.7 ± 2.0 kcal/mol, ΔHB0(YOIf ,298) = -208.8 ± 2.0 kcal/mol.
