The molar enthalpies of solution of sodium oxalate DsolHm(Na2C2O4; T=296.57 K, m= 0.00768 mol kg^-1)=(16.59+/-1.32) kJ mol^-1 and potassium oxalate monohydrate DsolHm(K2C2O4 H2O; 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, DsolHm((NH4)2C2O4 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.
