Abstract

The molar enthalpies of solution of sodium oxalate Δ _solH_m(Na₂C₂O₄; T = 296. 57 K, m = 0.00768 mol · kg^-1) = (16.59 ± 1.32) kJ ± mol^-1 and potassium oxalate monohydrate Δ _solH_m(K₂C₂O₄ H ₂O; T = 299.01 K, m = 0.0274 mol · kg^-1) = (29.31 ± 0.98) kJ · mol^-1 were calorimetrically determined. The case of ammonium oxalate monohydrate, Δ_solH _m(NH₄)₂O₄ · H₂O; T = 296.99 K; m = 0.03401 mol · kg^-1) = (35.0 ± 4.9) kJ · mol^-1 was previously considered in [11]. Solubilities of ammonium oxalate, sodium oxalate and potassium oxalate in water were measured in the (273 to 333) K temperature range. Presented data are compared with the literature results.
