What effect does a change in the concentration of ligands have on the formation of a complex ion in a solution of FeCl3? How does this affect the equilibrium constant of the reaction and what is the relationship between the concentration of the ligands and the stability constant of the complex ion? Calculate the equilibrium concentrations of the species involved and determine their values at different stages of the reaction. Use the given data and appropriate equations to solve the problem.
