摘要
氨气的喷泉实验是高中化学必修一的重要内容,主要是为了验证了氨气的极易溶于水与氨水为碱性的性质。本文针对这一实验,进行更为巧妙的设计,将氨气的制取,收集,和喷泉反应一体化,减少实验的耗材,并且加入氨气与浓盐酸的反应,无水硫酸铜与氨水的反应,提高实验效率。
The fountain experiment of ammonia gas is an important part of high school chemistry compulsory one, mainly to verify that ammonia gas is easily soluble in water and ammonia is alkaline. For this experiment, a more ingenious design was carried out to integrate the preparation and collection of ammonia gas with the fountain reaction to reduce the consumables of the experiment, and the reaction of ammonia gas and concentrated hydrochloric acid was added. The reaction between anhydrous copper sulfate and ammonia water Reaction to improve experiment efficiency.
