Fluoroantimonic acid - Wikipedia
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 −
Fluoroantimonic Acid: The Strongest Acid in the World
2023年10月3日 · Fluoroantimonic acid has an H 0 - 31.3. H 0 or Hammet acidity function is the same as the pH or power of hydrogen, but the difference is the pH value runs from 0 - 14 while the H 0 value runs below zero. The neutral pH is 7. A pH that is greater than 7 is more alkaline or basic, while a pH lower than 7 is acidic.
The World's Strongest Acid: A Deep Dive Into Extreme Acidity
2023年9月29日 · Given its potency, we can't use the regular pH or pKA scales to measure its strength. Here, the Hammett acidity function, denoted as H, steals the spotlight. Fluoroantimonic acid registers an H of -21, while sulfuric acid's H measures -12. To translate that, fluoroantimonic acid is a staggering 20 × 10¹⁹ times stronger than pure sulfuric acid.

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.
What Is the World's Strongest Superacid? - ThoughtCo
2024年8月3日 · The carborane superacids may be considered the world's strongest solo acid, as fluoroantimonic acid is actually a mixture of hydrofluoric 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 may be handled with bare skin. Teflon ...
Fluoroantimonic acid - Simple English Wikipedia, the free …
Acidity: Fluoroantimonic acid is often rated as around 10^16 times stronger than pure sulfuric acid, giving it one of the highest known acidities. pH: This acid is so strong that it doesn't have a measurable pH value in the traditional sense, as it readily donates protons in …
Strongest Acid pH - CHEMISTRY COMMUNITY - University of …
2023年12月6日 · In standard conditions, the concentration of hydrogen ions is between the pH values within the 0 to 14 range. However, in highly acidic solutions, where the concentration of hydrogen ions is greater than 1 M (such as in the case of fluoroantimonic acid), the negative logarithm of the hydrogen ion concentration can result in a negative pH value.
Fluoroantimonic Acid: World's Strongest Superacid?
2023年4月2日 · The pH of fluoroantimonic acid has been estimated to be around -14. It means that it is strongly acidic and can easily dissociate hydrogen ions (H+) in water or other solvents. However, it's important to note that the pH scale is logarithmic, which means that each change of one pH unit represents a tenfold change in acidity or alkalinity.
Fluoroantimonic Acid - HSbF6 - Kemicalinfo
Fluoroantimonic Acid pH. Fluoroantimonic acid is a superacid and has a pH value of less than -14. This is because the pH scale measures the concentration of hydrogen ions (H+) in a solution, and superacids have higher concentrations of H+ ions than pure water.
