Using the solution enthalpy of LaCl3 in 1.006 m hydrochloric acid, determined by Cordfunke et al. [36] as ΔsolH0(LaCl3) = – 126.39 ± 0.52 kJ mol−1 and the formation enthalpy of HCl in water (1 m), the formation enthalpy of LaCl3 can be calculated using a cycle analogous to...
The arrow pointing down from this to the lower thick line represents the enthalpy change of formation of sodium chloride. The Born-Haber cycle now imagines this formation of sodium chloride as happening in a whole set of small changes, most of which we know the enthalpy changes for - except,...
