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
Nonanoic acid Nonanoic acid Nonanoic acid, also called pelargonic acid, is an organic compound with structural formula CH(CH)COH. It is a nine-carbon fatty acid. Nonanoic acid is a colorless oily liquid with an unpleasant, rancid odor. It is nearly insoluble in water, but very soluble in organic solvents. The esters and salts of nonanoic acid are called nonanoates. Its refractive index is 1.4322. Its critical point is at 712 K (439 °C) and 2.35 MPa. Nonanoic acid occurs naturally as esters in the oil of pelargonium. Together with azelaic acid, it is produced industrially by ozonolysis of oleic acid. Synthetic esters of
