  2. Disulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Disulfuric_acid

    Disulfuric acid (alternative spelling disulphuric acid) or pyrosulfuric acid (alternative spelling pyrosulphuric acid), also named oleum, is a sulfur oxoacid. [3] It is a major constituent of fuming sulfuric acid, oleum, and this is how most chemists encounter it.

  3. Bunsen reaction - Wikipedia

    en.wikipedia.org/wiki/Bunsen_Reaction

    The Bunsen reaction is a chemical reaction that describes water, sulfur dioxide, and iodine reacting to form sulfuric acid and hydrogen iodide: . 2H 2 O + SO 2 + I 2 → H 2 SO 4 + 2HI ...

  4. Sulfurous acid - Wikipedia

    en.wikipedia.org/wiki/Sulfurous_acid

    Sulfurous acid is commonly known to not exist in its free state, and due to this, it is stated in textbooks that it cannot be isolated in the water-free form. [4] However, the molecule has been detected in the gas phase in 1988 by the dissociative ionization of diethyl sulfite. [5]

  5. Sulfur dioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_dioxide

    Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula S O 2.It is a colorless gas with a pungent smell that is responsible for the odor of burnt matches.

  6. Sulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Sulfuric_acid

    Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".

  7. Amine gas treating - Wikipedia

    en.wikipedia.org/wiki/Amine_gas_treating

    Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.

  8. Hydration reaction - Wikipedia

    en.wikipedia.org/wiki/Hydration_reaction

    The general chemical equation for the hydration of alkenes is the following: . RRC=CH 2 + H 2 O → RRC(OH)-CH 3. A hydroxyl group (OH −) attaches to one carbon of the double bond, and a proton (H +) adds to the other.

  9. Hydroboration–oxidation reaction - Wikipedia

    en.wikipedia.org/wiki/Hydroboration–oxidation...

    Hydroboration–oxidation reaction is a two-step hydration reaction that converts an alkene into an alcohol. [1] The process results in the syn addition of a hydrogen and a hydroxyl group where the double bond had been.
