ABSTRACT:
pH – metry investigation on the complex formation equilibrium of Ni2+, Co2+ and Mg2+ with Glycine (Gly) as a primary ligand and Oxalic acid (OXA) or Malonic acid (MAL) as a secondary ligand shows the formation of ternary systems. For present work different molar ratios of the metal, primary ligands and secondary ligands are used. The ionic strength of 0.1 Molar was kept constant using NaNO3. The complex formation equilibrium was elucidated with the help of speciation curves. The glycine and OXA or MAL with metal shows an order of Ni+2 > Co+2 > Mg+2
