在高中电化学教学中,有些必做经典实验如原电池反应原理实验、电解池反应原理实验以及电化学的应用实例等若用常规方法做,则所需化学仪器、药品等必然较多。当把上述物品在实验室、教师办公室、学生教室之间搬来搬去及组装拆卸时,不仅操作繁琐、浪费时间,而且稍有不慎就会使价格较贵的实验电源、灵敏电流计等仪器设备受损,从而影响实验效果。针对上述问题,笔者利用生活中简便易得的低成本材料和废旧物品等设计制作了便携式多功能电化学实验
In the high school electrochemical teaching, some must do the classic experiments such as the original battery reaction principle experiment, the electrolysis cell reaction principle experiment and the electrochemical application example, if uses the conventional method to do, then the required chemistry instrument, the medicine and so on are bound to be more. When the above items in the laboratory, teacher’s office, student classrooms move between the move and assembly and disassembly, not only tedious operation, a waste of time, and a little careless will make the more expensive experimental power supply, sensitive galvanometer Equipment damage, thus affecting the experimental results. In response to the above problems, the author uses the life of easy-to-use low-cost materials and waste products such as design and manufacture of portable multi-function electrochemical experiments
