  2. Sulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Sulfuric_acid

    Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid ...

    The limiting acid in a given solvent is the solvonium ion, such as H 3 O + ion in water.An acid which has more of a tendency to donate a hydrogen ion than the limiting acid will be a strong acid in the solvent considered, and will exist mostly or entirely in its dissociated form.

  6. Superacid - Wikipedia

    en.wikipedia.org/wiki/Superacid

    According to the modern definition, a superacid is a medium in which the chemical potential of the proton is higher than in pure sulfuric acid. [2] Commercially available superacids include trifluoromethanesulfonic acid ( CF 3 SO 3 H ), also known as triflic acid, and fluorosulfuric acid ( HSO 3 F ), both of which are about a thousand times ...

    The CIL catalyst used in ionikylation is non-hazardous and non-corrosive, which allows entire operating system to be constructed using carbon steel. [11] Three CIL alkylation units, each with 300,000 ton-per-year capacity, came online in China in 2019 at Sinopec ’s refineries in Jiujiang City, [ 12 ] Anqing City, and Wuhan City. [ 11 ]

  9. Chemical drain cleaners - Wikipedia

    en.wikipedia.org/wiki/Chemical_drain_cleaners

    Moreover, because the acidic or basic drain cleaners themselves are washed down the drain, this contributes to pollution in the water supply. Drain cleaners usually contain a strong base such as sodium hydroxide that decomposes hair and converts fats into water-soluble products. The reaction is exothermic, releasing heat to soften the fats.
