Thermodynamics for complex formation between palladium(II) and oxalate
Original language description
Complex formation between [Pd(H2O)4]2+ and oxalate (ox = C2O42-) has been studied spectrophoto-metrically in aqueous solution at variable temperature, ionic strength and pH. Thermodynamic parameters at 298.2 K and 1.00 M HClO4 ionic medium for the reaction [Pd(H2O)4]2+ + H2ox <-> [Pd(H2O)2(ox)] + H3O+ with equilibrium constant K1,H (in mol.dm-3) are log10K1,H = 3.38 ? 0.08, delta H0 = -33 +/- 3 kJ.mol-1, and deltaS0 = -48 +/- 11 J.K-1.mol-1, as determined from spectrophotometric equilibrium titrations at 15.0, 20.0, 25.0 and 31.0 degrees of Celsius. Thermodynamic overall stability constants Beta_n_0 (in (mol.dm-3)n) for [Pd(H2O)2(ox)] and [Pd(ox)2]2- at zero ionic strength and 298.2 K, defined as the equilibrium constants for the reaction Pd2+ +n ox2- <-> [Pd(ox)n]2-2n (water molecules omitted) are log10Beta_1 = 9.04 ? 0.06 and log10Beta_ = 13.1 +/- 0.
