Abstract

The hydrolysis-precipitation equilibrium reaction of aqueous gallium(III) solution was investigated in 0-3 mol-kg^-1 NaCl media at low pH at 100°C using a pressure-tight glass vessel. All precipitates were identified as GaOOH. The results were analyzed with a nonlinear least-squares computer program to obtain the solubility product K_so for gallium(III) oxyhydroxide using a single-parameter type of Debye-Hückel equation. The value of log K_so for GaOOH(s) + 3H⁺ ⇄ Ga³⁺ + 2H₂O was -0.60 at 100°C. The solubility product calculated from thermodynamic data was compared with the experimental result.
