一、为什么氨气极易溶解于水氨气易溶于水原因有两个方面:(1)氨分子和水分子很容易通过氢键结合形成一水合氨,即NH3+H2O(?)NH2·H2O;(2)NH3和H2O都是极性分子,根据相似相溶原理,由极性分子组成的溶质氨气易溶于由极性分子H2O组成的溶剂.所以NH3极易溶解于水.在常温、常压下,1体积水中能溶解约700体积的氨气.二、用氨做喷泉实验时要注意哪些问题(1)氨气要充满;(2)装置要不漏气;(3)氨 First, why ammonia is easily dissolved in water ammonia is soluble in water for two reasons: (1) ammonia molecules and water molecules can easily form hydrogenated ammonia through hydrogen bonds, namely NH3 + H2O (?) NH2 H2O; (2) NH3 and H2O are polar molecules. According to the principle of similar dissolution, solute ammonia composed of polar molecules is easily dissolved in the solvent consisting of polar molecules H2O. Therefore, NH3 is easily dissolved in water. Under normal temperature and pressure, one volume of water can dissolve about 700 volume of ammonia gas. Second, what problems should be paid attention when using ammonia as a fountain experiment (1) Ammonia should be full; (2) The device must not leak; (3) ammonia
