The hydrolysis of metal ions. Part 6. Scandium(III)
Abstract
The potentiometric titration technique has been used to study the hydrolytic behaviour of the scandium(III) ion in 0.10 mol dm–3 potassium nitrate at 25 °C. Data treatment indicates the presence of the species [Sc(OH)]2+, [Sc2(OH)2]4+, and [Sc3(OH)5]4+, the –log βpq values being 4.840 (0.008), 6.096 (0.004), and 17.567 (0.006) respectively; the estimated standard deviations are given in parentheses.
