fluoroantimonicacid
The molarity of carborane superacid will depend on the concentration of the acid solution. Carborane superacid is a strong acid with high acidity and is typically prepared in low concentrations due to its reactivity and potential hazards. Common concentrations for carborane superacid solutions range from 0.1 to 1 M.

Magic acid is the second most reactive Superacid behind fluoroantimonic acid. It is a superacid consisting of a mixture of fluorosulfonic acid (HSO3F) and antimony pentafluoride (SbF5). The name refers to its ability to protonate hydrocarbons, vividly demonstrated when a postdoctoral associate in the lab of George A. Olah used it to dissolve a candle.
According to Sam Kean, Carborane has a pH of -18 (see the Disappearing Spoon).
Considered safe in recommended doses. Possible allergic reaction, "superacid gastric complaints."
Carborane superacids are made by combining a carborane molecule, such as H(CHB11Cl11), with a Lewis acid like SbF5 or HF/SbF5. This creates a strong Brønsted acid that is more powerful than conventional mineral acids like sulfuric acid. The resulting carborane superacid has unique properties, making it a valuable catalyst for various chemical reactions.
Fluoroantimonic acid (HSbF6) is considered one of the strongest known Lewis acids. It is a superacid that can protonate hydrocarbons and other weak bases to form stable carbocations or other species.
The strongest acid that is known to exist is fluoroantimonic acid, HSbF6. This superacid is 1023 times more acidic than H3O+(the strongest acid that can exist in water) and will protonate even extremely weak bases (such as alkanes).
Fluoroantimonic acid (HSbF6) is a mixture of hydrogen fluoride and antimony pentafluoride in various ratios. The 1:1 combination forms the strongest known superacid, which has been demonstrated to protonate even hydrocarbons to afford carbocations and H2.It has a syrupy consistency and dissolves pretty much everything. It can be stored in Teflon bottles.
The world's most dangerous acid is Hydroflouric acid, which is actually classified as a weak acid, believe it or not. Perchloric acid gets my vote. No it isn't I thought it was carborane superacid. It was just discovered
Strongest (conjugated) Acid:hexa-Fluoro-Antimonic Acid (HSbF6 or HF.SbF5), pKa = -25It is conjugated to the base: SbF6-Classified as a "Superacid". This acid will donate proton to C2H4 to form a ethane-carbocation. Compare: pKa(HClO4) = -10, HClO4 does not react with ethene.
Carborane superacids, such as H(CHB11Cl11), are extremely strong acids that are used in various chemical reactions and as catalysts in organic synthesis. They are especially valuable in promoting reactions that require high acidity or in cases where traditional mineral acids are not effective.
