| Abstract: | Equilibrium study of the mixed ligand complex formation of FeIII with boric acid in the absence and in the presence of 2,2′-bipyridine, 1,10-phenanthroline, diethylenetriamine and triethylenetetramine (L) in different molar ratios provides evidence of formation of Fe(OH)2+, Fe(OH) 2 + , Fe(L)3+, Fe(H2BO4),Fe(OH)(H2BO4), Fe(OH)2(H2BO4)2-, Fe(L)(H2BO4) and Fe2(L)2(BO4)+ complexes. Fe(L) 2 3+ , Fe(L)2(H2BO4) and Fe2(L)4(BO4)+ complexes are also indicated with 2,2′-bipyridine and 1,10-phenanthroline. Complex formation equilibria and stability constants of the complexes at 25 ± 0.l°C in aqueous solution at a fixed ionic strength,I = 0.1 mol dm-3 (NaNO3) have been determined by potentiometric method. |
