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.

- Complex Equilibrium
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 ( Kf ). The formation of a complex ion by adding a complexing agent increases the solubility of a compound.
Complex-Ion Equilibrian II. 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. \ceAg(H2O)6+ \ce A g ( H 2 O) 6 +, \ceCu(H2O)62+ \ce C u ( H 2 O) 6 2 +, and \ceCr(H2O)62+ \ce C r ( H 2 O) 6 2 +, etc.
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.
Introduction. Dilute solutions of Fe (NCS)2+ have their equilibrium positions shifted with the addition of Fe (NO3)3, KSCN, NaOH, and AgNO3. Equations. The ferric thiocyanate solution is blood red in color, and the intensity of its color is proportional to the amount of complex in solution. The complex is formed according to the reaction:
