TO STUDIES CONDITIONAL STABILITY CONSTANT OF SUBSTITUTED THIOCARBAMIDOPHENOL WITH DIFFERENT TRANSITION METAL IONS COMPLEXES IN 70% ETHANOL-WATER SOLVENTS MEDIUM

Present work highlight the investigation of conditional stability constant and formation constant of metal-ligand complexes of ligands 4-(p-Chloro)phenylthiocarbamido phenol (L2) with Cu(II), Cd(II) , Cr(II) and Ni (II) metal ions with ethanol-water systems at different proportions by Jobs method of continuous variation. It is the spectrophototometric study. The stiochiometry of complex formation found to be 1:1. This investigation helps to understand drug effect and drug activity of newly synthesized drugs. Keywords: 4-(p-Chloro)phenylthiocarbamidophenol or (L2), stability constant, spectrophotometrically
