Abstract

The solubility measurements of sodium dicarboxylate salts; sodium oxalate, malonate, succinate, glutarate, and adipate in water at temperatures from (278.15 to 358.15 K) were determined. The molar enthalpies of solution at T = 298.15 K were derived: ?solHm (m = 2.11 mol · kg-1) = 13.86 kJ · mol-1 for sodium oxalate; ?solHm (m = 3.99 mol · kg-1) = 14.83 kJ · mol-1 for sodium malonate; ?solHm (m = 2.45 mol · kg-1) = 14.83 kJ · mol-1 for sodium succinate; ?solHm (m = 4.53 mol · kg-1) = 16.55 kJ · mol-1 for sodium glutarate, and ?solHm (m = 3.52 mol · kg-1) = 15.70 kJ · mol-1 for sodium adipate. The solubility value exhibits a prominent odd–even effect with respect to terms with odd number of sodium dicarboxylate carbon numbers showing much higher solubility. This odd–even effect may have implications for the relative abundance of these compounds in industrial applications and also in the atmospheric aerosols.
