Abstract
The hydrolysis of thorium(IV) in 0.10 mol dm–3 potassium nitrate has been investigated by potentiometric titration at 25 °C. Numerical analysis by our version of MINIQUAD has indicated that the only acceptable model involves the species [Th(OH)]3+, [Th4(OH)12]4+, and [Th6(OH)15]9+, for which the overall formation constants, expressed as –log βpq, are 2.98 (0.007), 30.55 (0.03), and 34.41 (0.03), the estimated standard deviations being given in parentheses.Keywords
