Superacid - Wikipedia
In chemistry, a superacid (according to the original definition) is an acid with an acidity greater than that of 100% pure sulfuric acid (H2SO4), [1] which has a Hammett acidity function (H0) of −12.
The World’s Strongest Acid – The Superacids - Science Notes …
2021年1月21日 · The world’s strongest acid is the superacid called fluoroantimonic acid (HSbF 6). It is over a billion times stronger than pure sulfuric acid. In other words, fluoroantimonic acid donates protons around a billion times better than sulfuric acid.
Examples of Superacids - Chemistry Examples
A superacid is defined as a substance that has a higher H + chemical potential than 100% pure sulfuric acid. List of Superacids. Acidity is indicated by the Hammett acidity function, H 0. Like pH, H 0 is a measure of acidity; lower values of H 0 mean higher protonating power. Like pH, H 0 is a logarithmic scale.
9.9: Superacids - Chemistry LibreTexts
Superbases such as lithium diethylamide (LiNEt 2), alkyllithium compounds (RLi), and Grignard reagents (RMgX) useful in a broad range of organic reactions. LiNEt 2 deprotonates C-H bonds to generate reactive carbanions. RLi and RMgX are powerful nucleophiles.

What’s the strongest acid in the world? | Article - RSC Education
For instance, hydrochloric acid comes in at about pH 1.6, nitric acid at 1.08 and pure sulfuric acid at a whopping pH -12. That makes sulfuric acid the strongest ‘normal’ acid you’ll find. Anything more powerful is defined as a superacid.
6.3.4: Brønsted-Lowry Superacids and the Hammett Acidity Function
Acids with an acidity greater than that of sulfuric acid are termed superacids. Superacids are able to dissociate completely because when they do so they give an extremely stable anion in which the residual negative charge is distributed among multiple electronegative atoms.
