| Abstract: | The complexation of Ho3+ in HoCl3 and KOH solutions at 25°C and saturated vapor pressure was studied by an indicator spectrophotometric technique, and the pH values of the investigated solutions were determined. The stability constants of the hydroxo complexes of Ho3+ were measured over a range of pH 9.25–10.10 and at μ≤ 4 × 10?4 and extrapolated to zero ionic strength. |
