一、氨1.氨的物理性质氨是没有颜色、有刺激性气味的气体;在标准状况下,氨的密度是0.771 g·L-1,比空气轻.氨极易溶于水且溶解得快,在常温下1体积水大约可溶解700体积氨.氨易液化,同时放出大量热,所以液氨常用作致冷剂.2.氨的化学性质(1)氨与水反应:氨溶于水时,大部分与水结合成一水合氨(NH3·H2O).NH3·H2O部分电离成NH+4和OH-,所以氨水
1. Ammonia 1. Physical properties of ammonia Ammonia is a non-colored, irritating gas. Under standard conditions, ammonia has a density of 0.771 g · L -1, which is lighter than air. Ammonia is readily soluble in water and dissolves Fast, at room temperature, a volume of water can dissolve about 700 volumes of ammonia ammonia easy to liquefy, and emit a lot of heat, so liquid ammonia commonly used as a refrigerant .2 chemical properties of ammonia (1) ammonia and water reaction: ammonia dissolved in Most of the water combined with water into ammonia monohydrate (NH3 · H2O). NH3 · H2O part of the ionization into NH +4 and OH-, ammonia
