Cf3so3h·h2o
WebFluorosulfuric acid ( IUPAC name: sulfurofluoridic acid) is the inorganic compound with the chemical formula HSO 3 F. It is one of the strongest acids commercially available. It is a tetrahedral molecule and is closely related to sulfuric acid, H 2 SO 4, substituting a fluorine atom for one of the hydroxyl groups. WebFor example, carbon dioxide, CO 2, is the anhydride of carbonic acid, H 2 CO 3, and sulfur trioxide, SO 3, is the anhydride of sulfuric acid, H 2 SO 4. These anhydrides react quickly with water and form those oxyacids again. [4] Many organic acids, like carboxylic acids and phenols, are oxyacids. [3]
