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.

Compare and contrast between complex ion and Lewis acid-base equilibria. 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.
Small, highly charged metal ions have the greatest tendency to act as Lewis acids and form complex ions. The equilibrium constant for the formation of the complex ion is the formation constant (K f). The formation of a complex ion by adding a complexing agent increases the solubility of a compound.
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.

Complex Ion Equilibria. A Lewis acid is a species that can accept an electron pair, whereas a Lewis base has an electron pair available for donation to a Lewis acid. Complex ions are examples of Lewis acid-base adducts and comprise central metal atoms or ions acting as Lewis acids bonded to molecules or ions called ligands that act as Lewis bases.
