Synthesis and Evaluate pK and Log K of 1(4-Aminophenyl)-2(p-Chlorophenyl thiocarbamido)-1-Ethanol with Cr(III), Cd(II) and Cu(II) ions pH-metrically

Present work deals with synthesis and evaluation of pK and Log K of 1(4-Aminophenyl)-2(p-Chlorophenyl thiocarbamido)-1-Ethanol with Cr(III), Cd(II) and Cu(II) ions pH-metrically. In present work studied proton-ligand stability constant (pK) and metal -ligand stability constant (log K) by interacting 1(4-Aminophenyl)-2(p-Chlorophenyl thiocarbamido)-1-Ethanol with Cr(III), Cd(II) and Cu(II) metal ions at 0.1 M ionic strength in 75 % ethanol-water mixture by Bjerrum method as adopted by Calvin and Wilson, It is observed that Cr(III), Cd(II) and Cu(II) metal ions form 1:1 with ligands [L]. The values of proton-ligand stability constant (pK) and metal-ligand stability constants (log k) were estimated and compared from resultant data. The effects of substituents were studied from estimated data (pK & log k).this work helps to understand solute-solute, solute-solvent and solvent-solvent interaction.
