Abstract

Stability constants of 2,3-dihydroxypropanoate complexes of
zinc(II), cr. clmium(II) and lead(II) were determined by potentiometric
titration in buffer solution using glass and quinhydrone
electrodes. All measurements were carried out at (298.2 ± 0.1) K
in buffer solutions of constant ionic strength of 2 mol dm-3• Stability
constants n:id their 95 per cent confidence intervals were calculated
on a digital computer using an algorithm described elsewhere11 •
On the basis of the obtained stability constants, different factors
governing the stability of the investigated complexes were discussed.
