Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in relation to
The Metal ion which is positively charged functions as a Lewis acid and Lewis base or the ligand has one or more lone pairs of electrons. For example, Cu2+, which is a highly charged and small metal ion having a significant tendency to function as Lewis acids, consequently exhibiting the highest affinity to form complex ions.
The development of a complexion is a stepwise procedure, and every step has its equilibrium constant. When two of the equations are added together, the equilibrium constants multiply. The Equilibrium Constant reflects the concentration in a reaction, which is the molarity, written as moles per liter(M = mol/L).
The products of a reaction are present in the numerator, and the denominator has the reactants. The alphabets in upper-case are the molar concentrations of the reactants and products, and the alphabets in lower-case are the
