Fluorosulfuric acid can be violent, similar to the addition of water to sulfuric acid but much more violent. Fluorosulfuric acid Fluorosulfuric acid (IUPAC name: sulfurofluoridic acid) is the inorganic compound with the chemical formula HSOF. It is one of the strongest acids commercially available. The formula HSOF emphasizes its relationship to sulfuric acid, HSO; HSOF is a tetrahedral molecule. It is a colourless liquid, although commercial samples are often yellow. Fluorosulfuric acid is a free-flowing colorless liquid. It is soluble in polar organic solvents (e.g. nitrobenzene, acetic acid, and ethyl acetate), but poorly soluble in nonpolar solvents such as alkanes. Reflecting its
Dihydroxymalonic acid Dihydroxymalonic acid Dihydroxymalonic acid is an organic compound with formula CHO or HO-(C=O)-C(OH)-(C=O)-OH, found in some plants such as alfalfa and in beet molasses. The compound may also be called dihydroxymesoxalic acid, dihydroxypropanedioic acid. It can be viewed as a hydrate derivative of mesoxalic acid, and indeed it is often called mesoxalic acid monohydrate and other silmilar names. This compound is unusual in containing stable geminal hydroxy groups. Dihydroxymalonic acid is a water-soluble white solid. It crystallizes in deliquescent prisms that melt between 113 °C and 121 °C without loss of water. It has been used in medical research as
