Abstract

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 •
