Abstract :

The ligand 2–Chloro– 2‘–hydroxy–4‘–chloro–5’methylchalcone oxime (CHCMCO) was developed as a new analytical reagent for the gravimetric and Spectrophotometric analysis of Ni (II) ion. In the pH range of 7.0 to 7.5, this reagent gives light green colored complex with Ni (II). Job‘s method of continuous variation and Yoe and Jone‘s mole ratio method revealed the stoichiometry of the complex to be 1:2 [M: L]. The obeyance of Beer‘s law was studied and the molar absorptivity was found to be 1.25 x 102 lit.mol–1cm–1. The reagent and its complex have been characterized by elemental analysis and IR spectra. The magnetic susceptibility measurement(4 ampere and 298o K) of the chelate has been calculated. The complex is diamagnetic in nature.
