Second Stability Constant

Go Second Stability Constant = (Formation Factor for Complexation*(Formation Factor for Second Order-1)*First Stability Constant*Ligand Concentration of the Complex)/(Ligand Concentration of the Complex*Ligand Concentration of the Complex*(2-Formation Factor for Complexation)*First Stability Constant)

Change in Stability Constant

Go Change in Stability Constant of the Complex = 10^(log10(Stability Constant for Ternary Complex)-(log10(Stability Constant for Binary Complex MA)+log10(Stability Constant for Binary Complex MB)))

Relation between First and Second Stability Constant

Go Second Stability Constant = 10^((2*pH of Ligand)+log10(Formation Factor for Complexation/((2-Formation Factor for Complexation)*First Stability Constant)))

First Stability Constant

Go First Stability Constant = 10^(log10(Formation Factor for Complexation/(1-Formation Factor for Complexation))+pH of Ligand)

Stability Constant of Ternary Complexes

Go Stability Constant for Ternary Complex = (Concentration of Ternary Complex)/(Concentration of Binary Ion*Ligand Concentration of the Complex)

Stability Constant of Binary Complexes

Go Stability Constant for Binary Complex = (Concentration of Binary Ion)/(Concentration of Metal in Complex*Ligand Concentration of the Complex)

Concentration of Unbound Ligand

Go Concentration of Unbound Ligand = Total Bound Ligand of Complex-(Formation Factor for Complexation*Total Metal Concentration of Complex)

Formation Factor

Go Formation Factor for Complexation = (Total Bound Ligand of Complex-Concentration of Unbound Ligand)/Total Metal Concentration of Complex

Total Metal Ligand Concentration

What is Complex Equlibra ?

A complex ion is comprised of two important parts: the central atom and its surrounding ligands. The central atom can be any metallic ion (usually a transition metal). The ligands are any combination of anions that can donate an electron pair, effectively meaning they are all Lewis bases. When combined they form coordinate covalent bonds. When a metal ion reacts with a Lewis base in solution a complex ion is formed. This reaction can be described in terms of chemical equilibria. Thus ,Complex ion equilibria are no exception to this and have their own unique equilibrium constant.
