Abstract | {Conjugate Bronsted-Lewis superacids in fluorosulfuric acid are studied by two techniques. Hammett acidity function studies on HSO3F-Ta(SO3F)(5) in the concentration range of 0-3.4 mol% of Lewis acid are reported. The conjugate system HSO3F-Ta(SO3F)(5) shows in this range of Lewis acid concentration acidities equal or higher to those of HSO3F-3SO(3)-SbF5, which is commonly assumed to be the strongest conjugate protonic acid. Electrical conductivities of the neat Lewis acids of the type MFn(SO3F)(5-n) |
