Sažetak

The stability constants of cadmium and copper monocarboxylato
complexes have been determined by the polarog raphic
method in water solutions of a constant ionic strength 2 and a
constant monocarboxylic acid concentration of 2 M. The examinations
were carried out in the monocarboxylate concentration
range up to 2 M. The following values of cumulative stability
constants were obtained:
Cadmium : formato complexes ~ 1 = 20 ± 2, ; Be = 50 ± 5,
p3 = 40 ± 8, p4 = 36 ± 8; acetato complexes P1 = 40±5, B2 = 110±10,
p3 = 110 ± 15, p4 = 215 ± 20; propionato complexes P1 = 30 ± 2,
B2 = 80 ± 20, Ps = 400 ± 50, p4 = 290 ± 30; butyrato complexes
P1 = 17 ±,2, B2 = 160 ± 20 , Bs = 400 ± 50, B4 = 480 ± 60.
Copper: formato complexes p1 = 45 ± 5, Bo.= 200 ± 30, ~ 3 =
= 200 ± 40 , B4 = 270 ± 40; acetato complexes Bi = 100 ± iO ,
B2 = 500 + 50, B3 = 1000 + 100 , P4 = 1250 + 200; propionato complexes
Bi= l.10 ± 10, B2 = 450 ± 50, Ba = 1100 ± 200 , B4 = 1100 ± 200,
B; = 950 ± 200; butyrato complexes B1 = 80 ± 10, P2 = 600 ± 100 ,
Ba = 2000 ± 300, B4 = 1700 ± 300, Ps = 2000 ± 300.
