You may be thinking the acid in the alien blood in the popular movie is pretty far-fetched, but the truth is, there’s is an acid that is even more corrosive! Learn about the word’s strongest superacid: fluoroantimonic acid.
The world’s strongest acid is fluoroantimonic acid, HSbF6. It is formed by mixing hydrogen fluoride (HF) and antimony pentafluoride (SbF5).
Various mixtures produce the superacid, but mixing equal ratios of the two acids produces the strongest superacid known to man.
Properties of Fluoroantimonic Acid Superacid
Rapidly and explosively decomposes upon contact with water. Because of this property, fluoroantimonic acid cannot be used in aqueous solution. It is only used in a solution of hydrofluoric acid.
Evolves highly toxic vapors. As the temperature is increased, fluoroantimonic acid decomposes and generates hydrogen fluoride gas (hydrofluoric acid).
Fluoroantimonic acid is 2×1019 (20 quintillion) times stronger than 100% sulfuric acid.1 Fluoroantimonic acid has a H0 (Hammett acidity function) value of -31.3.
Dissolves gl**** and many other materials and protonates nearly all organic compounds (such as everything in your body). This acid is stores in PTFE (polytetrafluoroethylene) containers.
