络合物稳定常数的测定对于络合物特别是内络合物的研究,颇为重要。因为积累了稳定常数的数据,可使人们对于络合物有比较全面的了解。同时,对于它们的形成和结构,对于中心离子和配位体之间键的本质和稳定性等也提供了有用的资料,由稳定常数可求出络合反应的热力学函数。 The determination of the stability constant of complexes is important for the study of complexes, especially internal complexes. Because of the accumulation of the data of the stability constant, people can have a more comprehensive understanding of the complex. At the same time, for their formation and structure, they also provide useful information for the nature and stability of the bond between the central ion and the ligand, and the thermodynamic function of the complexation reaction can be obtained from the stability constant.
