实验是中学化学学习和研究的一种方法,实验教学尤显重要,而教材中有些实验在实验设计、环境保护、药品用量等方面存在待改进的地方,从简化实验装置、节约药品用量等多方面对教材中“一氧化碳还原氧化铁实验”进行改进,体现了一体化微型实验在教学中的优势。经过改进的实验,大大缩短了实验所需的时间,降低了实验温度,减少了药品的用量,实验现象明显,污染减少,真正体现了绿色化学的本质。 Experiments are a method of chemistry study and research in middle school. Experimental teaching is especially important. Some experiments in teaching materials have some problems in experimental design, environmental protection, dosage of drugs and so on. From simplifying experimental devices and saving drug dosage In the textbook “carbon monoxide reduction iron oxide experiment” to improve, reflects the integration of micro-experiment in teaching advantages. The improved experiment greatly shortens the time required for the experiment, reduces the experimental temperature and reduces the dosage of the medicine. The experimental phenomenon is obvious, the pollution is reduced, and the essence of the green chemistry is really reflected.
