溶液导电性实验是引出强、弱电解质定义的奠基石,教师们都非常重视。课本中对实验装置介绍无几,装置的参数明了,作出的装置效果不理想。我在准备这一实验时,经查阅资料和与老师们探讨,成功地解决了有关问题: 1 灯泡的功率选多大原有装置上用的是“220V15W”的灯泡,实验时,五个灯泡的亮度几乎无差别。原理上应该有差别,为什 Solution conductivity experiment is the cornerstone of the definition of strong and weak electrolytes, and teachers attach great importance to it. Introduction to the experimental device in the textbook is very small, the device parameters clear, the effect of the device is not satisfactory. When I was preparing this experiment, I checked the materials and discussed with the teachers to successfully solve the problems: 1, the power of light bulbs is much larger than the original device is used, “220V15W” bulbs, the experiment, five The brightness of the light bulb is almost no difference. The principle should be different, why
