The stability of complexes depends upon stability constant. Higher the value of stability constant, more will be stability of complex. It can also be determined with the help of dissociation constant. Higher the value of dissociation constant, lesser will be stability. Smaller cation, with higher charge can form more stable complex. Stronger the ligand, more stable will be complex. Polydentate ligands form more stable complex than unidentate ligand. If multidentate ligand is cyclic, it further increases the stability, it is called macrocyclic effect. Formation of complex involves.
