Complex-Ion Equilibria. In general, chemical equilibrium is reached when the forward reaction rate is equal to the reverse reaction rate and can be described using an equilibrium constant, K. Complex ion equilibria are no exception to this and have their own unique equilibrium constant.

Describe and explain the concept of complex equilibria and stepwise equilibrium reactions. Use the concept of chemical equilibria in complexometric titrations and calculations. Distinguish among the various types of EDTA titrations and their uses.
Complex Equilibrium. Page ID. The lone pairs of electrons in water molecules make water an excellent ligand. Metal ions in any body of water in the environment usually are coordinated to 6 water molecules, e.g. Ag (H 2 O) 6+, Cu (H 2 O) 62+, and Cr (H 2 O) 62+, etc.

The equilibrium constant for the reaction between a metal ion and ligands produces a complex ion called a formation constant; for the reverse reaction, it is called a dissociation constant. Learning Objectives. By the end of this section, you will be able to: Explain the common ion effect. Explain the Lewis model of acid-base chemistry.
We begin our discussion of solubility and complexation equilibriums —those associated with the formation of complex ions—by developing quantitative methods for describing dissolution and precipitation reactions of ionic compounds in aqueous solution.
