Abstract :
Potentiometric study of ?–diketone complexes of iron, cobalt was carried out in aqueous media by titrating with standard NaOH solution. The complexes formation between Fe(II) and Co(II) metal ions and 1-(5-methoxythiophen-2-yl)-3-(2,4- dihydroxyphenyl)propane-1,3-dione (L) have been studied at 0.1 M ionic Strength at room temperature. It is observed that iron, cobalt, nickel and copper metal ions formed 1:1 and 1:2 complexes with ligands (L). The obtained data were used to compare the values of pH and metal-ligand stability constants.
