Potentiometric Studies of Some Binary Complexes of Cu(II), Ni(II), Co(II), and Mn(II) With Ligands Containing O-O Donar Atoms

Authors(1) :-Dr. J. R. Shukla

For the evaluation of stability constant of metal chelate, the proton ligand stability constant of the ligand is required. The values of proton ligand stability constant of Bis –(3-[{3-(3’,4’-dimethoxyphenyl)}-prop-2-enoyl]-4-hydroxy-6-methyl-2H-chromen-2-one)[M(II)], have been obtained at 300 ±  10 C by liner plot of pH against    log  ñA / 1 – ñA. At each point on straight line pH + log  ñA / 1 – ñA = pKH.  pK1H  and pK2values were obtained in the range ñ0 to 1 and 1 to 2 respectively. Irving and rossotti method has been employed for this potentiometric studies.
