如何提高高中学生的化学实验能力 ,我看应该充分重视平时实验过程中的思维发散。一、原理发散不要拘泥于教材上讲的原理 ,要坚持实事求是 ,只要是可行的 ,我们就可以尝试。如可以考虑用物理方法制气体 :用浓盐酸和浓硫酸制氯化氢 ,用氢氧化钠和浓氨水制氨气。用物理方法除杂提? How to improve the chemistry experiment ability of high school students, I think we should pay full attention to the divergence of thinking in the normal experiment process. First, the principle of divergence should not be rigidly adhered to the principle of teaching materials. We must adhere to the principle of seeking truth from facts. As long as it is feasible, we can try. If you can consider the use of physical methods gas: concentrated hydrochloric acid and concentrated sulfuric acid to hydrogen chloride, ammonia and concentrated ammonia to ammonia. Using physical methods to remove impurities?
