ABSTRACT:
Potentiometric studies have been carried out on transition metal complexes of Mn+2, Co+2, Ni+2, Cu+2, Zn+2 with hydrazones synthesized from 4-amino benzoic acid hydrazide and 2-hydroxy acetophenone/2-hydroxy-4methyl acetophenone. The dissociation constants of ligand and formation constants of its metal complexes have been determined by Calvin-Bjerrum pH titration technique, as adopted by Irving and Rossotti at 27±0.1ºC and at an ionic strength of 0.1M in 60:40 (v/v) dioxane water medium. The order of the stability of complexes is Cu+2 > Ni+2 > Co+2 > Mn+2 > Zn+2 for ligand AHEH and Co+2 > Cu+2 > Ni+2 > Mn+2 > Zn+2 for AMEH respectively. All the metal complexes screened for their antibacterial activity. The result indicates that the growth of the tested organism was inhibited by most of the compounds.
