Sodium hydroxide, also known as lye and caustic soda, 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 caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns.
Caustic (def) "able to burn or corrode organic tissue by chemical action." Pretty much all strong acids and bases fit this definition. Some weak acids, like glacial acidic acid, also has this property. It's a hazard class. The little symbol for it...
As its name implies, caustic soda is caustic and one of many alkaline compounds that are referred to as lye. NaOH, or pure sodium hydroxide, at room temperature is an odorless, white solid. Caustic soda should be used with caution, as it is an alkaline corrosive that can be hazardous.
As adjectives the difference between acid and caustic is that acid is sour, sharp, or biting to the taste; tart; having the taste of vinegar while caustic is capable of burning, corroding or destroying organic tissue. As nouns the difference between acid and caustic is that acid is a sour substance while caustic is any substance or means which, applied to animal or other organic tissue, burns ...
Caustic soda is one of the common names for sodium hydroxide (NaOH), which is also known as lye. Its common name derives from its chemical identity as a sodium hydrate and because it is caustic or corrosive. In pure form, caustic soda is a waxy, white solid. It readily absorbs water and forms aqueous solutions.
The deterioration can happen in minutes, e.g. concentrated muriatic acid spilled on skin; or slowly over days or years, e.g. the rusting of iron in a bridge. Sometimes the word caustic is used as a synonym for corrosive, but caustic refers only to strong bases, particularly alkalis, and not to acids, oxidizers, or other non-alkaline corrosives.
adj. c.1400, "burning, corrosive," from Latin causticus "burning, caustic," from Greek kaustikos "capable of burning; corrosive," from kaustos "combustible; burnt," verbal adjective from kaiein, the Greek word for "to burn" (transitive and intransitive) in all periods, of uncertain origin with no certain cognates outside Greek.Figurative sense of &...
A normal or neutral pH level is 7. Caustic soda is highly acidic with a pH of between 13.5 and 15. Caustic soda is a dangerous acid and should be handled carefully.
