Ligands were synthesized by the simple condensation reaction of Salicylaldehyde with 7 – Methoxy naphthalene – 2 – amine. Ligand was estimated for elements by standard methods. Nitrate salts of divalent metals cobalt, nickel, copper and zinc were estimated volumetrically as well as gravimetrically. pH metric titration were carried out with the help
of digital pH meter. Stability constant of complexes of these metals with ligand synthesized were computed by Irving Rossoti technique modified by Calvin Bjerrum1.
The stability constant values of metal complexes were found to be in the order Cu(II) > Ni (II) > Co (II) > Zn(II).
The observed results is in agreement with the natural order proposed by Irving – William2.
