| Abstract | ||
| This study involves the synthesis of new azodye, derived from 2-Amino-6-ethoxybenzothiazole and 4-Chloro-3,5-dimethylphenol . The characterization of dye has been described by C.H.N. The TG , IR and Visible. spectroscopic techniques.The acid-base properties were studied at different pH values .The ionization and protonation constants of dye were determined.Solvents effects were also studied at different solvents polarities . The optimum conditions of this formation of complex with Fe(III) were investigated . The analytical applications of thisazodye ,werestudied like; using it as acid-base indicator , and for the determination of nitrite ions . | ||
