?氨水价格

≥28% NH3 in H2O,电子级

Product Name: Ammonia solution

介绍:	为氨的水溶液。氨含量越多，密度越小。易挥发逸出氨气，有强烈的刺激性气味。能与乙醇混溶。呈强碱性。能从空气中吸收二氧化碳。与硫酸或其他强酸反应时放出热。与挥发性酸放在近处能形成烟雾。中等毒，半数致死量(大鼠，经口)355mg/kg。有腐蚀性。催泪性。
用途:	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。
特定比重:	0.9
贮存:	密封阴凉保存。
敏感性:	对二氧化碳敏感
生化和生理学机理:	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.
