WebMagic acid (FSO3H.SbF5) . It is a superacid consisting of a mixture, most commonly in a 1:1 molar ratio, of fluorosulfuric acid (HSO3F) and antimony pentafluoride (SbF5). It derives its name from the fact that it can dissolve otherwise undissolvable paraffin wax composed of inert long chain hydrocarbons.
