The determination of stability constants of L-glutamic acid gold (III) and mercury (II) complexes by potentiometric method
Dilek Arslan,Emre Dölen
The stability constants of the complexes which were formed L-glutamic acid with mercury(II) and gold(III) were determined potentiometrically by using CALVIN- BJERRUM and IRWING-ROSSOTTI methods, in this work. The protonation constants or dissociation constants of the ligand were found as logK1 or pK3 = 9,17 (NH+3); as log K2 or pK2 =3,95 (COOH) ; as log K3 or pK1 = 2,06 (COOH) at 25°C and for I = 0,22. Also the overall formation constants of complexes were found as logβ3 = 21.13 for mercury (II) ; as logβ3 Keywords :
