Caustic most commonly refers to: Causticity, the property of being able to corrode organic tissue. Sodium hydroxide, sometimes called caustic soda; Potassium hydroxide, sometimes called caustic potash; Calcium oxide, sometimes called caustic lime; Caustic may also refer to: Caustic (band), an American industrial/powernoise band
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
[10] [11] Sodium hydroxide is frequently used in the process of decomposing roadkill dumped in landfills by animal disposal contractors. [8] Due to its low cost and easy availability, it has also been used to dispose of corpses by criminals. Italian serial killer Leonarda Cianciulli used this chemical to turn dead bodies into soap. [12]
Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash.. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base.
Calcium oxide (formula: Ca O), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature . The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium ...
Potash was one of the most important industrial chemicals. It was refined from the ashes of broadleaved trees and produced primarily in the forested areas of Europe, Russia , and North America . Although methods for producing artificial alkalis were invented in the late 18th century, these did not become economical until the late 19th century ...
Sodium hydroxide is used in the manufacture of soap, paper, and the synthetic fiber rayon. Calcium hydroxide (slaked lime) is used in the manufacture of bleaching powder. Calcium hydroxide is also used to clean the sulfur dioxide , which is caused by the exhaust, that is found in power plants and factories.
Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate and ethanol: C 2 H 5 O 2 CCH 3 + NaOH → C 2 H 5 OH + NaO 2 CCH 3
