Acid \Ac"id\, a. [L. acidus sour, fr. the root ak to be sharp: cf. F. acide. Cf. Acute.]
Sour, sharp, or biting to the taste; tart; having the taste of vinegar: as, acid fruits or liquors. Also fig.: Sour-tempered.
He was stern and his face as acid as ever.
Of or pertaining to an acid; as, acid reaction.
Acid \Ac"id\, n.
A sour substance.
(Chem.) One of a class of compounds, generally but not always distinguished by their sour taste, solubility in water, and reddening of vegetable blue or violet colors. They are also characterized by the power of destroying the distinctive properties of alkalies or bases, combining with them to form salts, at the same time losing their own peculiar properties. They all contain hydrogen, united with a more negative element or radical, either alone, or more generally with oxygen, and take their names from this negative element or radical. Those which contain no oxygen are sometimes called hydracids in distinction from the others which are called oxygen acids or oxacids.
Note: In certain cases, sulphur, selenium, or tellurium may take the place of oxygen, and the corresponding compounds are called respectively sulphur acids or sulphacids, selenium acids, or tellurium acids. When the hydrogen of an acid is replaced by a positive element or radical, a salt is formed, and hence acids are sometimes named as salts of hydrogen; as hydrogen nitrate for nitric acid, hydrogen sulphate for sulphuric acid, etc. In the old chemistry the name acid was applied to the oxides of the negative or nonmetallic elements, now sometimes called anhydrides.
Douglas Harper's Etymology Dictionary
1620s, "of the taste of vinegar," from French acide (16c.) or directly from Latin acidus "sour, sharp," adjective of state from acere "to be sour," from PIE root *ak- "sharp, pointed" (see acrid). Figurative use from 1775; applied to intense colors from 1916. Acid test is American English, 1892, from the frontier days, when gold was distinguished from similar metals by application of nitric acid. Acid rain is first recorded 1859 in reference to England.
1690s, from acid (adj.). Slang meaning "LSD-25" first recorded 1966 (see LSD).\n\nWhen I was on acid I would see things that looked like beams of light, and I would hear things that sounded an awful lot like car horns.
[Mitch Hedberg, 1968-2005, U.S. stand-up comic]\nAcid rock (type played by or listen to by people using LSD) is also from 1966; acid house dance music style is 1988, probably from acid in the hallucinogenic sense + house "dance club DJ music style."
n. (context databases English) (acronym of atomicity, consistency, isolation, and durability English), a set of properties that guarantee database transactions are processed reliably
adj. harsh or corrosive in tone; "an acerbic tone piercing otherwise flowery prose"; "a barrage of acid comments"; "her acrid remarks make her many enemies"; "bitter words"; "blistering criticism"; "caustic jokes about political assassination, talk-show hosts and medical ethics"; "a sulfurous denunciation" [syn: acerb, acerbic, acrid, bitter, blistering, caustic, sulfurous, sulphurous, venomous, virulent, vitriolic]
containing acid; "an acid taste"
n. any of various water-soluble compounds having a sour taste and capable of turning litmus red and reacting with a base to form a salt
In computer science, ACID ( Atomicity, Consistency, Isolation, Durability) is a set of properties of database transactions. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction.
Jim Gray defined these properties of a reliable transaction system in the late 1970s and developed technologies to achieve them automatically.
In 1983, Andreas Reuter and Theo Härder coined the acronym ACID to describe them.
An acid is any chemical compound that, when dissolved in water, gives a solution with a pH less than 7.0.
Acid or ACID may also refer to:
Acid was a Japanese rock band originally created by Hideki after Siam Shade disbanded.
Acid (often written ACID; , ) is a Burmese hip hop group often credited with releasing Burma's first hip hop album, Beginning, in 2000. Two of the group's founders were later imprisoned for the group's allegedly pro-democracy lyrics.
Acid is a computer virus which infects .COM and .EXE files including [[command.com]]. Each time an infected file is executed, Acid infects all of the .EXE files in the current directory. Later, if an infected file is executed, it infects the .COM files in the current directory. Programs infected with Acid will have had the first 792 bytes of the host program overwritten with Acid's own code. There will be no file length increase unless the original host program was smaller than 792 bytes, in which case it will become 792 bytes in length. The program's date and time in the DOS disk directory listing will not be altered.
The following text strings are found in infected files:
- "*.EXE *.COM .."
- "Program too big to fit in memory"
- "Acid Virus"
- "Legalize ACiD and Pot"
- "By: Copyfright Corp-$MZU"
Usage examples of "acid".
It is useful in those diseases in which the fluids of the body are abnormally acid, as in rheumatism.
A plant of Drosera, with the edges of its leaves curled inwards, so as to form a temporary stomach, with the glands of the closely inflected tentacles pouring forth their acid secretion, which dissolves animal matter, afterwards to be absorbed, may be said to feed like an animal.
As for drinking, I am something of a chemist and I have yet to find a liquor that is free from traces of a number of poisons, some of them deadly, such as fusel oil, acetic acid, ethylacetate, acetaldehyde and furfurol.
If the proper materials, such as acid, coal gas, or acetaldehyde and a proper catalyst were available, then wood cellulose could be converted into ethyl alcohol.
Filter off the precipitate and wash with hot water containing a little sodium acetate, dissolve it off the filter with hot dilute hydrochloric acid, add ammonia in excess, and pass sulphuretted hydrogen for five minutes.
The precipitation of lead from acid solutions with sulphuric acid, and the solubility of the precipitate in ammonium acetate, distinguishes it from all other metals.
To convert, for example, a solution of a substance in hydrochloric acid into a solution of the same in acetic acid, alkali should be added in excess and then acetic acid.
The determination is rendered sharper and less liable to error by the addition of a few drops of acetic acid to convert the chromate into bichromate.
The small quantity of white flocculent precipitate which may be observed in the acetic acid solution before titrating, contains the whole of the iron as ferric arsenate.
Boil off the gas, add ammonia until a precipitate is formed, and then acidify somewhat strongly with acetic acid.
Add acetic acid until the solution is acid and the precipitate is quite dissolved.
The iron is reduced to the ferrous state and phosphate of alumina precipitated in an acetic acid solution.
From baryta, which it also resembles, it is distinguished by not yielding an insoluble chromate in an acetic acid solution, by the solubility of its chloride in alcohol, and by the fact that its sulphate is converted into carbonate on boiling with a solution formed of 3 parts of potassium carbonate and 1 of potassium sulphate.
In solutions rendered faintly acid with acetic acid, they give a yellow precipitate with bichromate of potash.
To separate these, ammonia is added till the solution is alkaline, and then acetic acid in slight excess.
