| Abstract | ||
| The complexes of the four amino acids with some metal salts of Fe(II) ,Ni(II) and Ca(II) were prepared and identified by spectro photometric methods (IR,UV) and magnetic measurements. Electro-conductivity measurements were done for these complexes in conductivity water at (310.16K) for each of (Glycine, Histidine, Argenine and Cystine).The value of (KA) association constant for nickel complexes is higher than iron and calcium complexes according to the metal ionic radius, while the value of ionic conductivity (λ˚M+2) for calcium complexes is more than nickel and iron complexes because of the affinity of calcium toward oxygen. The value of (R) (distance between ions in solution ) is more than Bjerrum constant which show that the complex ions are separated by solvent molecules (SSIP). The value of(σ( is found small and acceptable. | ||
