NH3极易溶于水,能与水发生反应生成显碱性的一水合氨,并且可以与盐酸反应产生白色烟。“自吹自擂”实验,是利用气体与溶液混合,发生反应,使瓶中压强急剧降低,造成外界大气压大于瓶中压强,把气球吸进集气瓶并被自动膨大鼓胀。这样可以验证气体的性质,非常有趣。通过探究,我们设计了NH“3自吹自擂”趣味实验。 NH3 easily soluble in water, can react with water to generate alkaline ammonia monohydrate, and can react with hydrochloric acid to produce white smoke. “Boast ” experiment, is the use of gas mixed with the solution, the reaction occurs, so that the sharp drop in pressure in the bottle, resulting in the external pressure is greater than the pressure in the bottle, the balloon into the gas collection bottle and was automatically bulging bulging. This is very interesting to verify the nature of the gas. Through exploration, we designed the NH “3 trumpery ” fun experiment.
