How do you make Fluoroantimonic acid?
Fluoroantimonic acid is made by combining hydrogen fluoride (HF) with antimony pentafluoride (SbF5), resulting in an acid that is 1016 times stronger than sulphuric acid. The hydrogen ion in HF is attached to fluorine by a very weak dipolar bond, which accounts for the extreme acidity of the superacid.
How is Sulphuric acid formed?
Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.
How is magic acid prepared?
Olah prepared the so-called magic acid, so-named for its ability to attack hydrocarbons, by mixing antimony pentafluoride (SbF5) and fluorosulfonic acid (FSO3H). The name was coined after a candle was placed in a sample of magic acid after a Christmas party.
Where is Fluoroantimonic acid found?
1 Fluoroantimonic acid has a H0 (Hammett acidity function) value of -31.3. Dissolves glass and many other materials and protonates nearly all organic compounds (such as everything in your body). This acid is stores in PTFE (polytetrafluoroethylene) containers.
How do you make a reaction to sulfuric acid?
Sulphuric acid is produced from sulphur. Sulphur dioxide is first obtained by the burning of the molten sulphur in presence of air. Sulphur dioxide is then converted to sulphur trioxide in presence of vanadium pentoxide catalyst.
How is sulphuric acid formed by contact process?
Sulphuric acid can be yielded by diluting sulphur trioxide in water. This is a very dangerous method and not followed. Adding sulphur trioxide to water is highly exothermic and causes the fuming of sulphuric acid. Further dissolution of sulphur trioxide in water is prevented by the fumes.
How is fluoride absorbed in the body?
When swallowed, fluoride is absorbed via the stomach and intestines, and passes rapidly round the body in the bloodstream. Peak blood levels appear in 30-60 minutes after swallowing. The most soluble fluoride compounds, such as sodium fluoride in water, tablets and toothpaste, are almost completely absorbed.
Why is HF so reactive?
Hydrogen an electronegativity of 2.2. The difference in electronegativity means that the Hydrogen atom has little of the electron density and is easily removed or separated from the Florine creating a high concentration of free Hydrogen ions H+1 This makes Hydroflouric acids extremely reactive.
Why is Fluorosulfuric acid a superacid?
It has an H0 value of −15.1 compared to −12 for sulfuric acid. The combination of HSO3F and the Lewis acid antimony pentafluoride produces “Magic acid”, which is a far stronger protonating agent. These acids all fall into the category of “superacids”, acids stronger than 100% sulfuric acid.
