(Tıp) (Alkalies). Kalevi, alkali: a) Bitki küllerinden elde edilen ve geniş ölçüde potasyum karbonat ve sodyum karbonat (deniz bitkileri) taşıyan tuzları anlatmak için eskiden kullanılan terim; b) Baz özelliğinde ve asitleri nötralleştirebilen maddelerin jenerik adı

Alkali metallerin hidroksitleriyle amonyum hidroksitin genel adı. Bu maddelerde, asitlerin kırmızıya çevirmiş olduğu bitkisel mavi rengi eski durumuna döndürme özelliği vardır
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
{n} a salt of an acrid, or caustic taste of, three kinds; vegetable fixed alkali, as potash; mineral fixed alkali, as soda; and volatile alkali, as ammoniac
In chemistry, a substance capable of forming hydroxyl (OH-) ions when dissolved in water Alkaline materials may be added to materials to neutralise acids or as an alkaline reserve or buffer for the purpose of counteracting acids which may form in the future While a number of chemicals may be used as alkaline buffers, the most common used in paper conservation are magnesium carbonate or calcium carbonate Alkalis can be neutralised by an acid to form a salt
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 chemical that: 1) is usually corrosive to human tissue and must be handled with care; 2) has a pH of more than 7 0; 3) neutralizes acids to form salts; 4) dissociates in water yielding hydroxide ions; 5) turns litmus paper blue; and 6) may also be called a base or caustic Common commercial alkalis are sodium carbonate (soda ash), caustic soda and caustic potash, lime, lye, waterglass, regular mortar, Portland cement, and bicarbonate of soda See Acid; Base; pH
Any compound having highly basic properties; i e , one that readily ionizes in aqueous solution to yield OH anions, with a pH above 7 0, and turns litmus paper blue Common commercial alkalis are sodium carbonate (soda ash), caustic soda and caustic potash, lime, lye, waterglass, regular mortar, portland cement, and bicarbonate of soda
any base or hydroxide having the following properties: (1) solubility in water, (2) the power of neutralizing acids, and (3) the property of altering the tint of many coloring matters
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"
In glassmaking, a soluble salt consisting mainly of potassium carbonate or sodium carbonate It is one of the essential ingredients of glass, generally accounting for about 15-20 percent of the batch The alkali is a flux, which reduces the melting point of the major constituent of glass, silica
any substance having basic (as opposed to acidic) properties In a restricted sense it is applied to the hydroxides of ammonium, lithium, potassium and sodium Alkaline materials in lubricating oils neutralize acids to prevent acidic and corrosive wear in internal combustion engines
A chemical substance which effectively neutralizes acid material so as to form neutral salts A base The opposite of acid Examples are ammonia and caustic soda
Any chemical substance that forms soluble soaps with fatty acids Alkalis are also referred to as bases They may cause severe burns to the skin Alkalis turn litmus paper blue and have pH values from 8 to l4
Any substance that in water solution is bitter, more or less irritating, or caustic to the skin Strong alkalies in solution are corrosive to the skin and mucous membranes
A molecular or ionic substance that can combine with a proton to produce a new compound (soaps, salts) A compound having highly basic properties, that readily ionises in aqueous solutions to yield OH anions, with a pH of above 7
(chem) (biocon) Any of various BASEs, which neutralize ACID to form SALT Bases are important in maintaining the chemical balance in a BIOGAS DIGESTER F - alcali S - alcali
Alkalis form chemical salts when they are combined with acids. ¡Ù acid. a substance that forms a chemical salt when combined with an acid (al-qili ). Inorganic compound, any soluble hydroxide (OH) of the alkali metals: lithium, sodium, potassium, rubidium, and cesium. More broadly, ammonium hydroxide (see ammonia) and soluble hydroxides of the alkaline earth metals are also called alkalies. Strong bases that turn litmus paper blue, they react with acids to yield salts, are caustic, and in concentrated form corrode tissues. Sodium hydroxide (caustic soda) and potassium hydroxide (caustic potash) are very important industrial chemicals, used in the manufacture of soaps, glass, and many other products. The mineral trona, a compound of sodium carbonate and bicarbonate, is one naturally occurring alkali. It may be mined or recovered from dry lake beds
