説明Disulfuric acid has the molecular formula of H2S2O7 where the S-atom is in the+5 oxidation state. It is a major constituent of fuming sulfuric acid (also known as “oleum”) described by the formula ySO3·H2O where y is the total molar sulfur trioxide content. They can also be described by the formula: H2SO4·xSO3, which are also minor constituents of liquid anhydrous sulfuric acid due to the equilibria: H2O+SO3→H2SO4+SO3→H2S2O7 Thus, the disulfuric acid is prepared by reacting excess SO3 with sulfuric acid: H2SO4+SO3→H2S2O7 Disulfuric acid is a strong acid and protonates sulfuric acid in the (anhydrous) sulfuric acid solvent system. An alternative IUPAC name is (sulfo-oxy)sulfonic acid.
