Polarographic Determination of Stability Constants of Glycerato Complexes of Cadmium and Lead
Stability constants of glycerato complexes of cadmium and
lead were determined by the polarographic method. Measurements
were performed in buffer solutions of sod1um salt of DL-glyceDic
acid. The concentration of the glyceric aoid in the buffer solutions
was constant: 0.0 7 M for cadmium, and 0.05 NI for lead. The ionic
strenght of solutions was 2 and -it was kept constant by m e ans of
sodium perchlorate . The following cumulative stability constants
were obta;ined: Cadmium: Bi = 40, B2 = 130, B3 = 340, B = 2.10.
Lead: [3 1 = 340, B2 = 5.7 X 10 3, Ba = 2.8 X 10 3, B4 = 4.8 X 10 3
