In this study a new organic Schiff base-azo ligand was prepared using two steps the condensation and diazotization reaction, this ligand used for reacting with the copper (II) ion to form a copper complex and determination small amounts of it, the prepared ligand and complex were characterized by UV-Vis, FT-IR, 1HNMR spectra, also measured Molar electrical conductivity for complex. Ion copper (II) was determined by a rapid, sensitive, simple and cheap spectrophotometric method, the copper compou
