Fluoroantimonic acid

April 9, 2007

Fluoroantimonic acid (HSbF6), the strongest known superacid, is made by combining HF with SbF5. It can be as much as 2 × 1019 times stronger than 100% H2SO4. However, superacids are all equally strong in aqueous solution; other solvents must be used to observe their effects.
