The interaction between Cu(II) and salicylic acid has shown 1:1 and 1:2 complex formation. The complex formation has been investigated pH metrically in different percentage of methanol-water and acetone-water mixture at temperature (29oC + 0.1oC). The method Bjerrem and Kelvin as modified by Irving and rossotti has been used in the present work. It shows that proton – ligand and metal – ligand stability constant increased with increasing the percentages of methanol – water and acetone – water.
