The work of Germann and his students has definitely established that Phosgene is a Mother Solvent for a system of acids, bases, and salts. The acids are capable of reacting with metals and bases of this system to form salts. By neutralizing phosgenoaluminic acid with the anhydrous halides of Lithium, Magnesium, Potassium and Lead, their respective salts are obtained. The Potassium and Lead salts are difficult to work with because they form crusts at the end of the Faraday tubes. Lithium and Magneseum form LiAlCl4 and Mg2Al5Cl19 respectively. By a study of the pressure-concentration curves, these salts have been shown to be associated. Fourteen molecules of the sodium salt, twelve of strontium and about seventy of barium are associated to give single molecules. That of barium is of colloidal magnitude.
