Stability Constant of Metal LIG and Complex
Keywords:
Stability constant, metal-ligand complex, coordination chemistry, chelate effect, potentiometric methods, spectrophotometry, bioinorganic chemistry, catalysisAbstract
This paper explores the stability constant of metal-ligand complexes, a key parameter in coordination chemistry that defines the affinity between a metal ion and its ligand. By examining methods of determination, including potentiometric, spectrophotometric, and conductometric techniques, the study emphasizes the accuracy and applicability of different experimental approaches. Results demonstrate that factors such as metal ion charge, ligand denticity, solvent polarity, and temperature significantly affect stability. The analysis reveals that chelating ligands enhance complex stability due to the chelate effect, while environmental conditions further modify equilibrium constants. The findings confirm that stability constants play a pivotal role in advancing applications in bioinorganic chemistry, drug design, catalysis, and environmental remediation.
