别名 阿摩尼亚水;Ammonium water; Ammonia aqueous; Ammonium hydroxide; Aqua ammonium
生化机理 Ammonium hydroxide supplied in solution [NH3(aq)] with approximately 28-30% NH3; it appears as a colorless liquid, free from suspended matter or sediment. Aqueous ammonia is used in the laboratory most often as a complexant and base in inorganic analysis. Can also dissolve silver residues. With copper(II) solutions, gives a deep blue coloration. Ammonium hydroxide has also been used as an alternative for decalcifying bone specimens prior to histological examination.
应用 分析试剂，中和剂，生物碱浸出剂。用于某些元素（如铜、镍）的检定和测定。用以沉淀出各种元素的氢氧化物。制备铵化合物，洗涤剂，比色测定。
