Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid ...
a highly corrosive, strong mineral acid with many industrial uses Hydrofluoric acid: valued source of fluorine, precursor to numerous pharmaceuticals; highly corrosive Hydrogen peroxide: an oxidizer commonly used as a bleach Imidazole: an organic compound; this aromatic heterocyclic is a diazole and is classified as an alkaloid: Isopropyl alcohol
Mineral acids are also used directly for their corrosive properties. For example, a dilute solution of hydrochloric acid is used for removing the deposits from the inside of boilers, with precautions taken to prevent the corrosion of the boiler by the acid. This process is known as descaling. [citation needed]
Ammonium sulfate (American English and international scientific usage; ammonium sulphate in British English); (NH 4) 2 SO 4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.
It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. [11] Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777.
The following are examples of superacids. Each is listed with its Hammett acidity function, [10] where a smaller value of H 0 (in these cases, more negative) indicates a stronger acid. Fluoroantimonic acid (HF:SbF 5, H 0 = -28) Magic acid (HSO 3 F:SbF 5, H 0 = −23) Carborane acids (H(HCB 11 X 11), H 0 ≤ −18, indirectly determined and ...
Examples of superacids are fluoroantimonic acid and magic acid. Some superacids can be crystallised. [10] They can also quantitatively stabilize carbocations. [11] Lewis acids reacting with Lewis bases in gas phase and non-aqueous solvents have been classified in the ECW model, and it has been shown that there is no one order of acid strengths ...
These gases are highly corrosive to any downstream equipment such as fans, ducts, and stacks. Two methods that may minimize corrosion are: (1) reheating the gases to above their dew point, or (2) using materials of construction and designs that allow equipment to withstand the corrosive conditions. Both alternatives are expensive.
