pH-Potentiometric Investigation towards Chelating Tendencies of -Hydroquinone and Phenol Iminodiacetate Copper(II) Complexes
Figure 3
Species distribution (% formation relative to Cu2+) in the Cu(II)-cacp system at equimolar concentration (5.00 mmol ) as a function of pH over the range 2.00–10.0 (, mol KCl, , ). The Cu(II) species are as follows: (a) [Cu(H2cacp)(H2O)], (b) [Cu(H2cacp)2]2−, (c) [Cu(Hcacp)(H2O)]−, (d) , and (e) .
