中文百科

碱 Alkali

(重定向自Alkalis)

在各种酸碱理论中,都是指与酸相对的一类物质。碱多指碱金属及碱土金属的氢氧化物,而对碱最常见的定义是根据阿伦尼乌斯(Arrhenius)提出的酸碱离子理论作出的定义:碱是一种在水溶液中可以电离出氢氧根离子并且不产生其它阴离子的化合物。随后这个定义被扩展为提供氢氧根或者吸收氢离子的化合物。

根据不同的酸碱理论,碱有着不同的定义。

英语百科

Alkali 碱

(重定向自Alkalis)

In chemistry, an alkali (/ˈælkəl/; from Arabic: al-qaly القلي, القالي , “ashes of the saltwort”) is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline is commonly, and alkalescent less often, used in English as a synonym for basic, especially for soluble bases. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases.
