Recently, a lot of work has been performed on the acid-base properties of Lewis acidic molten salts. One of the most extensively investigated melt systems is the sodium chloroaluminate melt (175{degrees}-220{degrees}C) in which the chloride ion activity is dependent upon the composition of the melt. It is well known that unusual higher oxidation state ionic species, such as S(IV) or lower oxidation state cluster compounds, such as W{sub 6}CI{sub 8}{sup 4 +}, can be stable in the chloroaluminate melts because of the strong Lewis acidity of these solvents. These melts are now one of the potential solvents. These melts are now one of the potential materials for use in low-temperature molten salt batteries or as solvents for organic syntheses. The aluminum bromide-sodium bromide melts also show the variable Lewis acidity. Some physical properties of the haloaluminate melts are dependent on the halide species. Therefore, the acid-base properties of the melts also may vary with the anion component, even with the same cationic constituent. The authors discuss how they investigated the acid-base properties of the AIBr{sub 3}-NaBr melts and compared their characteristics with those of the chloroaluminate melts.
