摘要：

Thermodynamic data for palladium(II) in Pd2+-OH--ClO4- system were obtained through critical reviews and reinterpretations of literature data using the Bronsted-Guggenheim-Scatchard Model. The solubility product of palladium(II) hydroxide, hydrolysis constant of palladium(II), and ion interaction coefficients between palladium(II) species and electrolyte ions were determined with 95% confidence interval. The thermodynamic data thus obtained help accurately predict the solubility-limiting concentrations of palladium(II) as a function of hydrogen ion concentration in dilute to relatively concentrated solutions.
