According to Baidu Baike, when the molar ratio of HF to SbF5 is 1:1 (fluorantimonic acid), its acidity can be as much as 1019 times that of anhydrous sulfuric acid, making it the strongest superacid known. These superacids, such as magic acid, are mixed acids prepared by combining antimony pentafluoride and fluorosulfonic acid in a volume ratio of 1:1. Its acidity is only 10 million times that of anhydrous sulfuric acid. Dear expert, how much superacid needs to be added to increase the acidity of a 1000 kg solution of 20% dilute sulfuric acid to 25%? Like magic acid. How much does adding a small amount of magic acid increase the acidity?
Pure hydromolybdic acid is highly acidic, but that doesn’t mean it is also highly acidic in aqueous solutions… Practical experience shows that in water, fluorantimonic acid behaves no differently from strong acids such as sulfuric acid and hydrochloric acid, which undergo complete ionization.
