A Thermochemical Study of the Reaction of Lanthanum Nitrate with Alanine

摘要

The standard molar reaction enthalpy of the solid-solid coordination reaction La(NO_3)_3· 6H_2O (s) + 4Ala (s) (Ala is Alanine) =La (NO_3)_3·(Ala)_4·H_2O(s) + 5H_2O(1) was studied by using classical solution calorimetry. The molar dissolution enthalpies of the reactants and the product of the solid-solid coordination reaction in 2 mol/L HCl were measured by using an isoperibol calorimeter.
