Abstract

The complexs formation between lead(II) and aspartate or glutamate has bees studied by measuring the electromotive force of galvanic cells containing glass and stationary diluited amalgam electrodes at 25°C and in 1.00M NaClO4. Experimental data have been explained by assuming the presence of species PbL, PbHL, PbH2L, PbL2,PbH2L2; PbH3L2 and PbH4L2 where L indicates aspartate or glutamate. The stability constants of each complex have been determined showing that protonated species prevail in a wide range of coincentration of reagents. Results have been compared with those obtained for glycine and serine.
