  2. Fluoroantimonic acid - Wikipedia

    en.wikipedia.org/wiki/Fluoroantimonic_acid

    Fluoroantimonic acid is a mixture of hydrogen fluoride and antimony penta­fluoride, containing various cations and anions (the simplest being H 2 F + and Sb F − 6).This mixture is a superacid that, in terms of corrosiveness, is trillions of times stronger than pure sulfuric acid when measured by its Hammett acidity function.

  3. Superacid - Wikipedia

    en.wikipedia.org/wiki/Superacid

    In chemistry, a superacid (according to the original definition) is an acid with an acidity greater than that of 100% pure sulfuric acid (H 2 SO 4), [1] which has a Hammett acidity function (H 0) of −12. According to the modern definition, a superacid is a medium in which the chemical potential of the proton is higher than in pure sulfuric ...

    en.wikipedia.org/wiki/Superbase

    The Schlosser base (or Lochmann-Schlosser base), the combination of n-butyllithium and potassium tert-butoxide, is commonly cited as a superbase. n -Butyllithium and potassium tert -butoxide form a mixed aggregate of greater reactivity than either component reagent.

    en.wikipedia.org/wiki/Magic_acid

    Magic acid (FSO 3 H·SbF 5) is a superacid consisting of a mixture, most commonly in a 1:1 molar ratio, of fluorosulfuric acid (HSO 3 F) and antimony pentafluoride (SbF 5).This conjugate Brønsted–Lewis superacid system was developed in the 1960s by Ronald Gillespie and his team at McMaster University, [1] and has been used by George Olah to stabilise carbocations and hypercoordinated ...

  8. Base (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Base_(chemistry)

    A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca(OH)

  9. Cyanide - Wikipedia

    en.wikipedia.org/wiki/Cyanide

    In chemistry, cyanide (from Greek kyanos 'dark blue') is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. [1] In inorganic cyanides, the cyanide group is present as the cyanide anion − C≡N. This anion is extremely poisonous.
