The standard formation enthalpy of the glycine complex with erbium chloride was determined by using an isoperibolic calorimeter with the hydrochloric acid solution(2 mol/L) as a calorimetric solvent according a proposed thermochemical cycle. The following values were obtained: Δ_rH_m^θ(298.15 K)=-3.331 kJ/mol Δ_fH_m^θ(Er(Gly)₃Cl₃·3H₂O,s,298.15 K)=-3 632.0 kJ/mol
- glycine complex,
- erbium chloride,
- standard formation reaction enthalpy,
- calorimetric determination
