Calorimetric Determination of Formation Enthalpy of the Complex of Alanine with Samarium Nitrate
Abstract:
The dissolution enthalpies of the[Sm(NO3)3·6H2O(s)+4Ala(s)] and Sm(Ala)4(NO3)3·H2O(s) have been measured at 298.15 K using a homemade isoperibolic calorimeter with hydrochloric acid solution(2 mol/L) as solvent.The standard molar enthalpy of the coodination reaction of alanine with samarium nitrate has been determined via a designed thermochemical cycle, and ΔHr,mθ=21.393 kJ/mol was obtained.The standard molar enthalpy of formation of the complex Sm(Ala)4-(NO3)3·H2O has been calculated to be ΔHf,mθ [Sm(Ala)4(NO3)3·H2O,s,298.15 K]=-3 865.2 kJ/mol.
