alkali Anlamı

• 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 14. 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.
• A Substance which neutralizes acids; calcium, potassium or sodium. any base or hydroxide having the following properties: solubility in water, the power of neutralizing acids, and the property of altering the tint of many coloring matters.
• A molecular or ionic substance that can combine with a proton to produce a new compound A compound having highly basic properties, that readily ionises in aqueous solutions to yield OH anions, with a pH of above 7.
• 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.
• An alkaline, or 'basic,' chemical substance such as lime or lye Generally present in fresh cement, concrete, or plaster.
• Historically, a compound that neutralizes acids Now known as a base.
• A substance that is the chemical opposite of an acid.
• Any strongly basic substance of hydroxide and carbonate, such as soda, potash, etc , that is soluble in water and increases the pH of a solution.
• 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 soluble mineral salt or a mixture of soluble salts, present in some soils, esp in arid regions, and detrimental to the growing of most crops.
• A soluble hydroxide of a metal substance which can be used to neutralizes acids.
• 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 , caustic soda and caustic potash, lime, lye, waterglass, regular mortar, portland cement, and bicarbonate of soda.
• Mineral salt found in soil.
• 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 , caustic soda and caustic potash, lime, lye, waterglass, regular mortar, Portland cement, and bicarbonate of soda See Acid; Base; pH.
• A soluble mineral salt. an acid-neutralizing substance.
• Same as Base A substance which dissolves in water and releases a hydroxyl ion ; it has the ability to neutralize an acid and form a salt Strong alkalis are irritating and may damage tissue.
• Also called base - A Class of compounds which will react with an acid to give a salt Alkali is the opposite of acid. 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.
• Any substance having basic 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.
• 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 having basic 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.
• In chemistry, a substance capable of forming hydroxyl 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.
• 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.
• base.
• Soluble mineral matter, other than common salt, contained in soils of natural waters. a mixture of soluble salts found in arid soils and some bodies of water; detrimental to agriculture.
• 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.
• Soda ash; caustic soda, caustic potash, etc.
• alkali.
• alkali. alcali.
