巧用棉柔巾做可视化的电解实验

Skillfully Using Cotton Towel for Visual Electrolysis Experiments

利用生活中常见的棉柔巾和紫甘蓝等物品,设计了一种小巧的可视化电解装置,实现将微观离子的移动转化为宏观颜色的迁移。新设计的可视化电解装置具有结构简单、操作简便、现象明显、耗时短、充满趣味性和普适性等优点,便于开展学生分组实验,能有效帮助学生理解电解原理。

A visual mini-electrolysis device was designed by using the common objects such as cotton towel and purple cabbage,this device could characterize the movement of microscopic ions by macroscopic color migration.The new electrolysis device had the advantages of simple structure,easy operation,obvious phenomenon,short time,full of interest and universality.It was very convenient for students to carry out group experiments and could effectively help students understand the principle of electrolysis.
