Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H 2 SO 4. It is a colorless, odorless, and viscous liquid that is miscible with water. [7] Structure ...
They can also be described by the formula H 2 SO 4 ·xSO 3 where x is now defined as the molar free sulfur trioxide content. Oleum is generally assessed according to the free SO 3 content by mass. It can also be expressed as a percentage of sulfuric acid strength; for oleum concentrations, that would be over 100%.
Sulfuric(IV) acid (United Kingdom spelling: sulphuric(IV) acid), also known as sulfurous (UK: sulphurous) acid and thionic acid, [citation needed] is the chemical compound with the formula H 2 SO 3. Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO 2 molecule and the bisulfite ion, HSO − 3. [2]

A chemical formula used for a series of compounds that differ from each other by a constant unit is called a general formula. It generates a homologous series of chemical formulae. For example, alcohols may be represented by the formula C n H 2n + 1 OH (n ≥ 1), giving the homologs methanol, ethanol, propanol for 1 ≤ n ≤ 3.
The mechanism of the formation of ethyl sulfate, diethyl ether, and ethylene is based on the reaction between ethanol and sulfuric acid, which involves protonation of the ethanolic oxygen to form the [vague] oxonium ion.
Silver sulfate precipitates as a solid when an aqueous solution of silver nitrate is treated with sulfuric acid: . 2 AgNO 3 + H 2 SO 4 → Ag 2 SO 4 + 2 HNO 3. It is purified by recrystallization from concentrated sulfuric acid, a step that expels traces of nitrate. [7]
Fluorosulfuric 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. It is a colourless liquid ...
