Sažetak

The half-wave potential of the metal ion is shifted to more
positive values when the concentration of the monocarboxylic acid
in the monocarboxylate buffer increases. At low monocarboxylic
acid concentrations, in which no hydrolysis of complexes occurs,
there is a linear relation between the half-wave potential and acid
concentration. It makes possible the determination of the limit acid
concentration in which no hydrolysis of complexes has yet occurred.
At such conditions the stability constants of the formato, acetato,
propionato, butyrato, and lactato complexes of copper, zinc,
cadmium, and lead were determined.
