Preparation of Beta-Diketone Complex under Potentiometric Study with Fe (II) and Co (II) Transition Metal Ions
Keywords:
Potentiometric Study, bita–Diketone, Metal ions, pH and Stability ConstantAbstract
Potentiometric study of bita–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.
