Sažetak

By the polarographic method of DeFord and Hume the
stability constants of plumbous monocarboxylato co mplexes have
been determined, in water solutions of a constant ionic s trength 2
and a con stant concentration of 2 M of monocarboxylic acid. The
examinations were carried out in the monocarboxyla te concent r a t ion
range up to 2 M. The following values of stability const a nts were
obtained: formiato complexes /31= 13, /32 = 50, /33 = 30; acetato complexes /31 = 150 , /32 = 900, fJ3 = 3000; propionato complexes fJ 1 = 170, /J2 = 2200, /J3 = 5800 ; butyrato complexes /J 1 = 120 , /32 = 2000 , /3 3 = = 5800. It i s evident that with the increase of b ase strength and the size of the monoc arboxylate ion the complex stability increas es in the m'ljority of cases.
