  • Abstract

    A new series of some mercerized azodyes, 2-( 2-mercury chloride -4-X phenylazo)-4-acetamido phenol (where X = sulphonic acid [L1], acetyl [L2],carboxyl [L3], nitro [L4] and sulphamide [L5]) were prepared. All these were characterized by melting points, FT IR-spectroscopy 1H NMR and C H N analysis. The work involves a study of acid - base properties at different pH values, the ionization and protonation constants were calculated. The complexes of L1 and L5 with Cu(II) were prepared. These complexes have been concluding after fixing the optimum conditions (time, pH and sequence of addition effects). The spectra of the complexes solutions have been studied for a range of concentrations which Lambert – Beer’s law obeyed. It was found that the complexes are 1: 2 (M:L) complexes and the overall stability constants were determined by the corresponding solutions method
