Abstract
The interactions of Cu(II), Cd(II) and Cr(III) metal ions with 5-phenylthiocarbamido-1-naphthol(L2) and 5-p-clorophenylthiocarbamido-1-naphthol (L3) have been studied at 0.1 M ionic strength in 70 % ethanol-water mixture by Bjerrum method as adopted by Calvin and Wilson, It is observed that Cu(II), Cd(II) and Cr(III) metal ions simultaneously form the 1:1 and 1:2 complexes with ligands (L2 and L3). The values of proton-ligand stability constant (pK) and metal-ligand stability constants (log k) were estimate and compared from resultant data. The effects of substituents were studied from estimated data (pK & log k).
