中文百科

氨水

氨水(NH3[aq])常称为阿摩尼亚水,指氨气的水溶液,有强烈刺鼻气味,具弱碱性。

氨水中,氨气分子发生微弱水解生成氢氧根离子及铵根离子。“氢氧化铵”事实上并不存在,只是对氨水溶液中的离子的描述,并无法从溶液中分离出来。

氨的在水中的电离可以表示为:

反应平衡常数Kb = 1.8×10。

\mathrm{K_b={[NH_4^+][OH^-]\over[NH_3]}}

1M氨水的pH值为11.63,大约有0.42%的NH3变为NH4

氨水是实验室中氨的常用来源。它可与含铜(II)离子的溶液作用生成深蓝色的配合物,也可用于配置银氨溶液等分析化学试剂。

英语百科

Ammonium hydroxide 氨水

Ammonia solution, also known as ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or simply ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH3(aq). Although the name ammonium hydroxide suggests an alkali with composition [NH4][OH], it is actually impossible to isolate samples of NH4OH, as these ions do not comprise a significant fraction of the total amount of ammonia except in extremely dilute solutions.
