دراسة ثوابت الاستقرارية لبعض معقدات ايونات الفلزات مع الليكاند (ثنائي (3- هيدروكسي نفثالين -1- حامض السلفونيك ) 5,2-هكسان ثنائي امين ).

Abstract

Ionization constant of Bis – ( 3 - hydroxy naphthalene -1- sulfonic acid) 2,5- Hexane diimine) (N2O2)has been determined , value of (4.82 x 10-6 )was recommended measurement of stability constant of complexes formed by ( N2O2 ) with Hg+2 ,Cd +2, Zn+2 , Cu +2, Ni +2, Co+2 , Fe +2 ,Mn+2 . Ions have been performed . A bi dentate ligand (N2O2) has of hardness parameter( α ) of (1.91 ) and softness parameter ( β )( 3.39 ) , It,scomplexesbeingformed were of (1:1)ratio .
