Formation Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Formation Factor for Complexation = (Total Bound Ligand of Complex-Concentration of Unbound Ligand)/Total Metal Concentration of Complex
n_factor = (T_CL°-L_complex)/T_CM°
This formula uses 4 Variables

Variables Used

Formation Factor for Complexation - Formation Factor for Complexation is the ratio of the total concentration of the ligand bound to the metal ion to the total concentration of the metal ion.
Total Bound Ligand of Complex - (Measured in Mole per Cubic Meter) - Total Bound Ligand of Complex is the concentration of the ligand that is involved in complexation.
Concentration of Unbound Ligand - (Measured in Mole per Cubic Meter) - Concentration of Unbound Ligand is the concentration of the ligands that do not form complex to the metal ion.
Total Metal Concentration of Complex - (Measured in Mole per Cubic Meter) - Total Metal Concentration of complex is the concentration of the metal ion involved in complexation.

STEP 1: Convert Input(s) to Base Unit

Total Bound Ligand of Complex: 0.25 Mole per Liter --> 250 Mole per Cubic Meter (Check conversion here)
Concentration of Unbound Ligand: 0.2 Mole per Liter --> 200 Mole per Cubic Meter (Check conversion here)
Total Metal Concentration of Complex: 0.09 Mole per Liter --> 90 Mole per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n_factor = (T_CL°-L_complex)/T_CM° --> (250-200)/90

Evaluating ... ...

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

Go Total Metal Ligand Concentration of Complex = Total Metal Concentration of Complex+Total Bound Ligand of Complex

Ligand Stoichiometry in Complex Equilibrium

Go Stoichiometric Coefficient of Lewis Base = Maxima of pL Curve/(1-Maxima of pL Curve)

pH of Ligand

Go pH of Ligand = -log10(Ligand Concentration of the Complex)

Stability Constant of Complex Compound

Go Stability Constant of Complex = 1/Dissociation Constant of the Complex

Formation Factor Formula

Formation Factor for Complexation = (Total Bound Ligand of Complex-Concentration of Unbound Ligand)/Total Metal Concentration of Complex
n_factor = (T_CL°-L_complex)/T_CM°

What is Ionic Strength ?

Ionic strength refers to a measure of the concentration of ions present in a particular solution. Ionic compounds can certainly dissolve in water. On dissolving in water, they dissociate into ions.
