人教版化学选修6实验化学教材中有“水的电解与氢氧混合气爆鸣的微型实验”。从教学实践看,该实验存在电解速度慢、现象不明显等缺点,有必要加以改进。在找到原因后,通过改变电极材料、增大电极表面积等措施,能够加快电解速度,增强实验效果,并具有携带和使用方便的特点。 PEP chemical selective 6 experimental chemistry textbooks have “electrolysis of water and hydrogen and oxygen mixed gas explosion micro experiment ”. From the perspective of teaching practice, the experiment has some shortcomings such as slow electrolysis and insignificant phenomena, which needs to be improved. After finding out the reasons, by changing the electrode material, increasing the electrode surface area and other measures, can speed up the electrolysis, enhance the experimental results, and has the characteristics of easy to carry and use.
