alkali

Noun

1. Soda ash; caustic soda, caustic potash, etc.
2. (Chemistry) One of a class of caustic bases, such as soda, potash, ammonia, and lithia, whose distinguishing peculiarities are solubility in alcohol and water, uniting with oils and fats to form soap, neutralizing and forming salts with acids, turning to brown several vegetable yellows, and changing reddened litmus to blue.
3. (Western United States) Soluble mineral matter, other than common salt, contained in soils of natural waters.

• Definitions:
• Any substance having basic (as opposed to acidic) properties. In a restricted sense it is applied to the hydroxides of ammonium, lithium ...
• Various soluble salts, principally of sodium, potassium, magnesium, and calcium, that have the property of combining with acids to form neutral salts and may be used in chemical water treatment processes.
• Mineral salt found in soil.
• A substance such as lye, soda or lime that can be highly destructive to paint films.
• A chemical substance (such as hydroxide or carbonate of sodium or potassium) which reacts and neutralizes an acid.
• A soluble mineral salt.
• A chemical "base" (loosely, the opposite of an acid). Certain types of alkalis (especially potassium hydroxide) have been used as fuel cell electrolytes.
• a chemical substance. An alkali has a pH above 7 and turns litmus paper blue. It is soluble in water, neutralizes acids and forms salts with them
• A general term referring to any basic material (pH greater than 7). Historically, 'alkali' referred to hydroxides and carbonates of sodium and potassium. Alkalis act as fluxes in ceramics and glass production-enabling silica to melt at lower temperatures.
• (al·ka·li) (al´k?-li) [Arabic al-qal?y potash] any of a class of compounds which form soluble soaps with fatty acids, turn red litmus blue, have pH values greater than 7.0, and form soluble carbonates. ...
• Africa and Middle East Moslem judge or lay magistrate who administers Mohammedan law.
• Metals - Elements in Group 1 on the periodic table.
• A chemical substance that, when dissolved in water, creates a hydrogen ion concentration lower than 10-7 moles/liter. This term has also been used with paper products to imply the inclusion of an alkaline buffer.
• A water soluble hydroxide on one of the alkali metals. The term is virually synonymous with the term base. An example is Sodium Hydroxide, NaOH.
• A chemical substance that can neutralize an acid. Also refers to soluble salts in soil, surface water, or groundwater. 1
• Same as Base. A substance which dissolves in water and releases a hydroxyl ion (OH-); it has the ability to neutralize an acid and form a salt. Strong alkalis are irritating and may damage tissue (see Caustic).
• a soluble salt that is one of the essential ingredients in making glass, serving as a flux to reduce the fusion point of the silica; alkali is supplied in borax, soda or potash.
• acid neutralizing substance. A soluble salt with base properties..
• Any substance that neutralizes acids. Alkalis are helpful in aqueous cleaning by speeding soil removal and suspension. Alkali is synonymous with caustic.
• Chemical agent, generally soluble in water, capable of neutralizing acids. Usually caustics; pH of 7 is neutral, up to 14 indicates degree of alkalinity base.
• A soluble base ; pH 8–14.
• see: KASEI SODA, KIBAI, SEKKAI, SODA BAI Chemicals that are added during the cooking process to help dissolve the non-cellulose materials in the bast fibers. The most commonly used alkalis are (from strongest to weakest) caustic soda, soda ash, lime and wood ash.
• a liquid with a pH higher than 7. Alkalis are used in depilatory creams that dissolve hair, and galvanic electrolysis produces alkalis which can destroy a hair follicle
• a classification of substances that liberate hydroxide ions in water, to form caustic and corrosive solutions which turn litmus paper blue, with a pH higher than 7, for example sodium Hydroxide. A compound that reacts with or neutralizes hydrogen ions.
• a solution containing an excess of free hydroxyl ions, with a pH greater than seven
• base: any of various water-soluble compounds capable of turning litmus blue and reacting with an acid to form a salt and water; "bases include oxides and hydroxides of metals and ammonia" a mixture of soluble salts found in arid soils and some bodies of water; detrimental to agriculture
• In chemistry, an alkali (from Arabic: al-qaly??????, ?????? ) is a basic, ionic salt of an alkali metal or alkali earth metal element. Alkalis are best known for being bases (compounds with pH greater than 7) that dissolve in water. ...
