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 − 6).This mixture is a superacid that, in terms of corrosiveness, is trillions of times stronger than pure sulfuric acid when measured by its Hammett acidity function.
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
Commercially available superacids include trifluoromethanesulfonic acid (CF 3 SO 3 H), also known as triflic acid, and fluorosulfuric acid (HSO 3 F), both of which are about a thousand times stronger (i.e. have more negative H 0 values) than sulfuric acid. Most strong superacids are prepared by the combination of a strong Lewis acid and a ...
Nitrobenzene is prepared by nitration of benzene with a mixture of concentrated sulfuric acid, water, and nitric acid. This mixture is sometimes called "mixed acid." The production of nitrobenzene is one of the most dangerous processes conducted in the chemical industry because of the exothermicity of the reaction (ΔH = −117 kJ/mol). [5] +

Cyanide poisoning can result from the ingestion of cyanide salts, imbibing pure liquid prussic acid, skin absorption of prussic acid, intravenous infusion of nitroprusside for hypertensive crisis, [8] or the inhalation of hydrogen cyanide gas. The last typically occurs through one of three mechanisms:
And it is within these edgy curves that shepherds produce casu marzu, a maggot-infested cheese that, in 2009, the Guinness World Record proclaimed the world’s most dangerous cheese.
