Abstract :

 The interaction between Co(ll), Ni(ll) and Cu(ll) Metal Ions and 2–Hydroxy–4–Methyl–5–Chloro Acetophenone (L1) and Benzophenone have been studied at 0.1M Ionic Strength in 70% DMF water mixture by Bjerrum method as adopted by Calvin and Wilson. It is observed that Co(ll), Ni(ll) and Cu(ll) Metal ions form 1:1 and 1:2 complexes with ligands (L1 & L2). The data obtained were used to estimate and compare the values of proton–ligand stability constant (pK) and metal–ligand stability constants (log k). From estimated data (pK and log k), the effects of substituents were studied.
