Abstract
The thermodynamic relations of chemical equilibrium of the multi-steps reactions in aqueous solutions are roughly summarized for calorimetric measurements of the reactions of metal-ligand complex formation.
Two types of the computational analysis of enthalpy measurements are introduced, the one calculates the enthalpies by using the known equilibrium constants come from the other measurements and the other simultaneously obtains the enthalpies and the equilibrium constants. A few types of calorimeters which have ever used are introduced and the titration calorimeter is favourable because of the needs of many successive data for the enthalpy measurements of the reactions of metal-ligand complex formation.
