The hydrolysis of metal ions. Part 4. Indium(III)

Abstract

The hydrolysis of indium(III) has been investigated by potentiometric titration at 25 °C in 0.10 mol dm^–3 potassium nitrate. Data treatment by our version of MINIQUAD has shown the ‘best’ model to be [In(OH)]²⁺,[In(OH)₂]⁺, and [In_p(OH)_p]^2p+; the –log β_pq values for these species are estimated to be 4.31 (0.003), 9.35 (0.01), and 7.32 (0.006)(p= 4) or 9.12 (0.009)(p= 5) respectively, the estimated standard deviations being given in parentheses.
