Strongest Acid Ever made


strongest acid



You may be thinking the acid within the alien blood in popular movie is pretty far-fetched, but the reality is, there's is an acid that's even more corrosive! Learn about the word's strongest superacid: fluoroantimonic acid. 


Strongest Superacid
The world's strongest superacid is fluoroantimonic acid, HSbF6. It is formed by mixing H-fluoride (HF) and antimony pentafluoride (SbF5). Various mixtures produce the superacid, but mixing equal ratios of the 2 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 can't be utilized in solution . It is only utilized in an answer of acid .
Evolves highly toxic vapors. As the temperature is increased, fluoroantimonic acid decomposes and generates H-flouride gas (hydrofluoric acid).
Fluoroantimonic acid is 2×10^19 (20 quintillion) times powerful than 100% oil of vitriol .1 Fluoroantimonic acid features a H0 (Hammett acidity function) value of -31.3.
Dissolves glass and lots of other materials and protonates nearly all organic compounds (such as everything in your body). This acid is stores in PTFE (polytetrafluoroethylene) containers.

What Is It Used For?
If it is so toxic and dangerous, why would anyone want to possess fluoroantimonic acid? The answer lies in its extreme properties. Fluoroantimonic acid is employed in chemical engineering and chemistry to protonate organic compounds, in spite of their solvent. For example, the acid are often wont to remove H2 from isobutane and methane from neopentane. It is used as a catalyst for alkylations and acylations in petrochemistry. Superacids normally are wont to synthesize and characterize carbocations.

Reaction Between Hydrofluoric Acid and Antimony Pentafluoride
The reaction between H-flouride and antimony pentrafluoride that forms fluoroantimonic acid is exothermic.

HF + SbF5 → H+ SbF6-

The H-ion (proton) attaches to the fluorine via a really weak dipolar bond. The weak bond accounts for the intense acidity of fluoroantimonic acid, allowing the proton to leap between anion clusters.

What Makes Fluoroantimonic Acid a Superacid?
A superacid is any acid that's stronger than pure oil of vitriol, H2SO4. By stronger, it means the superacid loses more protons or hydrogen ions in water or includes a hammet acidity function of H0 less than -12. Hammet acidity function of fluorantimonic acid is H0 = -28.


Other Superacids
Other superacids includes carborane superacids [e.g, H(CHB11Cl11)] & fluorosulfuric acid (HFSO3). The carborane superacids is additionally considered because the world's strongest solo acid, as fluoroantimonic acid is basically a mixture of H-flouride acid and antimony pentafluoride. Carborane has a pH value of -18. Unlike fluorosulfuric acid and fluoroantimonic acid, the carborane acids are so noncorrosive that they'll be handled with bare skin. Teflon, the non-stick coating often found on cookware, might contain carbonate. Carborane acids are relatively uncommon, so it's unlikely a chemistry student would encounter one amongst them.

Strongest Superacid Key Takeaways
A superacid has an acidity greater than that of pure oil of vitriol.
The world's strongest superacid is fluoroantimonic acid.
Fluoroantimonic acid is the mixture of H-fluoric acid and antimony pentafluoride.
The carbonane superacids are the strongest solo acids.
