Vexed Question

The experiments described in this paper were undertaken in the hope of obtaining some light upon the vexed question of the condition in which a solid exists when dissolved in a liquid, and were directed more especially towards the investigation of the well-known remarkable phenomena exhibited by sodium sulphate. Crystallised sodium sulphate melts at about 34°, and at this temperature the salt begins to show signs of dissociation by depositing the anhydrous compound. According to Wiedemann, indeed, indications of change are observable at a few degrees lower. He finds by observation of the volume of the crystallised salt at different temperatures, that whereas slight expansion occurs from 17° to about 30°, contraction then sets in, at first slowly, then, at 33° to 34°, very rapidly, till the salt melts. The melted salt expands regularly in proportion as the temperature is raised to near 100°. Nicol has made experiments upon the expansion of solutions of the same salt, and with similar results.

As Effects

Molar enthalpies of dissolution of aluminium chlorides, bromides, and iodides in acetonitrile and tetrahydrofuran at 295 K have been determined experimentally. results of the measurements carried out in presence of air humidity point to the fact that both solvents preferential solvation of the solute by water molecules takes place. In an inert atmosphere, all the values obtained are negative. molar heat of dissolution has for AlCl3 the lowest negative value: -181 kJ mol-1 in acetonitrile and -107.8 kJ mol-1 in tetrahydrofuran. For AlBr3 and AlI3 exothermicity of dissolution is considerably higher: -817 and -887 kJ mol-1 for acetonitrile, and -489 and -713 kJ mol-1 for tetrahydrofuran. The transfer from water into both organic solvents has an endothermic character for AlCl3 only; for AlBr3 and AlI3, the character of transfer is unambiguously exothermic. The obtained results are interpreted as effects of interaction between the solute and the solvent.
