    abstract = {The complexation equilibria of glycine with some transition metal ions such as Cu<SUP>2+</SUP>, Co<SUP>2+</SUP> and Ni<SUP>2+</SUP> were studied by potentiometric method in aqueous solution. All of the titration steps were carried out at 25.0&plusmn;0.1&deg;C and ionic strength (&mu;) of 0.1 M supported by NaNO<SUB>3</SUB>. The overall stability constants log&#946;&#146;s of respective species were evaluated by computer refinement of the corresponding potentiometric pH titration data using BEST computer program. The corresponding distribution diagrams were depicted as a function of pH by using SP and SPE programs. The most likely species were obtained from distribution diagrams. Complex stabilities follow the trend copper(II)&gt;nickel(II)&gt;cobalt(II) which is in agreement with the Irving-Williams series.}
