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 Cu (II)
ion. In the pH range of 6.0 to 6.5, this reagent gives buff colored complex with Cu (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, the molar absorptivity was found to be
1.07x102lit.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 reveals the
paramagnetic nature of the complex.
