| 설명 | 물에 녹는 염기성 물질을 통틀어 이르는 말. OH－ 이온을 함유하는 물질을 말한다. 수산화나트륨, 수산화칼륨 따위의 알칼리 금속과 알칼리 토금속의 수산화물로, 그 수용액은 붉은 리트머스 종이를 푸른색으로 변화시킨다. 이것은 지방산과 함께 가용성 비누를 형성하고, 가용성 탄산염을 형성하는 화합물이다. |

| metals, alkali | Metals that constitute group ia in the periodic table. They are the most strongly electropositive of the metals. (12 Dec 1998) |
|---|---|
| metals, alkaline earth | Metals that constitute the group IIa in the periodic table. (12 Dec 1998) |
| metals | Electropositive chemical elements characterised by ductility, malleability, luster, and conductance of heat and electricity. They can replace the hydrogen of an acid and form bases with hydroxyl radicals. (12 Dec 1998) |
|---|---|
| metals, actinoid | A series of radioactive elements from actinium, atomic number 89, to and including lawrencium, atomic number 103. They are the theoretical analogs of the rare earth metal series. (12 Dec 1998) |
| metals, heavy | metals with high specific gravity, typically larger than 5. They have complex spectra, form coloured salts and double salts, have a low electrode potential, are mainly amphoteric, yield weak bases and weak acids, and are oxidizing or reducing agents (12 Dec 1998) |
| metals, light | Metals with low specific gravity, typically smaller than 5, characterised by a single valence (1, 2, or 3), a simple spectrum, strong electromotive force (positive), and colourless compounds. (12 Dec 1998) |
| metals, rare earth | Elements of group IIIb of the periodic table from lanthanum, atomic number 57, to and including lutetium, atomic number 71. (12 Dec 1998) |
| alkali | Origin: F. Alcali, ultimately fr. Ar. Alqali ashes of the plant saltwort, fr. Qalay to roast in a pan, fry. 1. Soda ash; caustic soda, caustic potash, etc. 2. <chemistry> One of a class of caustic bases, such as soda, potash, ammoma, and lithia, whose distinguishing peculiarities are solubility in alcohol and water, uniting with oils and fats to form soap, neutralising and forming salts with acids, turning to brown several vegetable yellows, and changing reddened litmus to blue. Fixed alkalies, potash and soda. Vegetable alkalies. Same as Alkaloids. Volatile alkali, ammonia, so called in distinction from the fixed alkalies. Source: Websters Dictionary (01 Mar 1998) |
| alkali denaturation test | A test for haemoglobin F (Hb F), based on the fact that haemoglobins, with the exception of Hb F, are denatured by alkali to alkaline haematin; the test is sensitive to 2% or more Hb F. (05 Mar 2000) |
| alkali disease | A term applied to various animal poisonings of plant and mineral origin in arid regions under the belief that they were caused by the ingestion of alkaline waters; e.g., botulism of wild ducks, caused by feeding on decayed vegetation in nearly dried-up lakes. (05 Mar 2000) |
| alkali earth metal | See: alkaline earth elements. (05 Mar 2000) |
| alkali metal | <chemistry> Any of the highly reactive metals (such as sodium or potassium) found in the first column of the periodic table, these metals act as bases. (13 Nov 1997) |
| alkali reserve | The sum total of the basic ions (mainly bicarbonates) of the blood and other body fluids which, acting as buffers, maintain the normal pH of the blood. (05 Mar 2000) |
| alkali sink | <ecology> A land basin in which water evaporation produces high salt concentrations that may, or may not, support salt marsh vegetation. (13 Nov 1997) |
| vegetable alkali | A mixture of potassium hydroxide and carbonate. (05 Mar 2000) |
| caustic alkali | A highly ionised (in solution) alkali; e.g., NaOH. (05 Mar 2000) |
| milk-alkali syndrome | <syndrome> A form of metabolic acidosis that can result from the excessive consumption of milk (calcium) and antacids (sodium bicarbonate) over a prolonged period of time. This can result in calcium deposits in the kidneys and body tissues. Symptoms include nausea, vomiting and weakness. May be seen as a complication of peptic ulcer therapy. (27 Sep 1997) |
