A Review of Stability Constants with a Reference of Schiff Bases

A comprehensive review with a focus on Schiff bases

Abstract

A stability constant (also known as a formation constant or a binding constant) is anequilibrium constant that controls the formation of a complex in solution. It is a metric measuring theintensity of the interaction between the reagents that produce the complex. Compounds generated bythe interaction of a metal ion with a ligand and supramolecular complexes, such as host—guestcomplexes and anions complexes, are the two types of complexes. The stability constant(s) are used tocompute the concentration(s) of the complex(es) in solution. There are several applications in chemistry,biology and medicine. In this paper stability constants with a reference of Schiff bases are reviewed.
