Post Graduate College, Gyanpur, Sanr Ravi Das Nagar, Bhadohi -221304 (INDIA) <p style="text-align: justify;">Modified electrophoresis technique viz. solution electrophoresis has been employed for the study of the metal ligand equilibira in solution. The method is based upon the migration of metal ion under electric influence in electrophoretic tube with variation in pH of the black ground electrolyte (ionic strength 0.1). The plot of pH Vs absorbance difference reveals the nature of complexation and help in calculating its equilibrium constants. The present work report the result on the binary viz. Cu(II), Ni(II), Co(II) and Zn(II)-Glycyl Glycine complexing system.</p> https://journalofchemistry.org/paper/585/ electrophoresis technique
