The standard molar enthalpy of solution of CeBr3(s) in 0.25 molโขdm -3 HCl(aq) has been measured. From that value, combined with auxiliary values, the standard molar enthalpy of formation has been derived: DfHยฐm{CeBr3,s, 298.15 K}=-(891.421.0) kJโขmol -1 .
The standard molar enthalpies of solution of CeCl3(s) in HCl(aq) of concentration 0.234 molโขdm -3 , and LaCl3(s) in HCl(aq) of concentration 1.006 molโขdm -3 have been measured. From these values the standard molar enthalpies of formation have been derived: DfHยฐm(CeCl3,s,298.15 K) = -(1060.5 2 0.5) k
The standard molar enthalpies of solution of 4DyBr3(s) + KCl(s)5, 4DyI3(s) + KCl(s)5, 4DyCl3(s) + KBr(s)5, and 4DyCl3(s) + KI(s)5 in 0.1025 molโขdm -3 HCl(aq) have been measured. From these values the standard molar enthalpies of formation of DyBr3(s) and DyI3(s) have been derived: DfHยฐm (DyBr3, s, 2
The standard molar enthalpies of solution of Dy metal and monoclinic DyCl3(s) in 4.0 molโขdm -3 HCl(aq), and of NdCl3(s) in 2.3 molโขdm -3 and 4.0 molโขdm -3 HCl(aq) have been measured. From these values, the standard molar enthalpies of formation have been derived: DfHยฐm(DyCl3, s, T = 298.15 K) = -(99
