高中焰色反应化学实验的改善方法分析

The Analysis on the Method of Improving High School Chemistry Experiment of the Flame Reaction

在高中化学实验中,焰色反应是非常重要的实验内容之一,也是教学大纲中要求我们所必须要掌握的知识,它可以有效检验钾离子、钠离子等,而且操作方便。但是这一实验也存在着一些不足,需要进行优化,同时我们学生通过对不同的化学实验进行优化改进,将自己的所思所想运用到化学实验学习中,能够体验到新奇与乐趣,从而培养起对高中化学的学习兴趣,增强探索物质变化的能力。本文主要分析了教材书中提及的焰色反应检验方法的不足,在此基础上提出了相应的实验优化改进方法,希望能够为其他同学学习焰色反应实验时提供参考。

In the high school chemistry experiment, the flame is one of the important contents of the experimental requirements, we must master the knowledge but also the teaching syllabus, it can effectively test the potassium ion and sodium ion,and the operation is convenient. But it also has some shortcomings, need to be optimized at the same time, we optimize the students through the chemical experiment for different, their thinking is applied to chemical experiment learning, be able to experience the novelty and fun, so as to cultivate the high school chemistry learning interest, enhance the ability to explore the changes of substances. This paper mainly analyzes the deficiency of flame reaction test methods mentioned in the textbooks,put forward the corresponding improvement method of experimental optimization, hope can provide reference for other students to learn the flame reaction experiment.
