一、问题的提出现行人教版高中化学教材中设置的原电池实验,盐桥制作繁琐、电解质溶液消耗较多且转移不方便。基于此,笔者尝试对原电池实验进行重新设计,以方便教师课堂演示及学生分组实验。海洋宝宝是一种吸水后膨胀的玩具,广泛应用于鱼缸或花瓶等的填充物,海洋宝宝的主要成分是聚丙烯酸钠,吸水性好,颜色丰富多彩,吸水后体积膨胀约十倍,且吸水后质软易破裂。将海洋宝宝运用于原电池实验的设计,不仅新颖独特,且实验操作简捷,现象明显。二、微型原电池实验设计
First, the question is made Pedestrian teach version of high school chemistry textbooks set up the original battery experiment, salt bridge cumbersome, more electrolyte solution consumption and transfer inconvenient. Based on this, I try to re-design the original battery experiment to facilitate teacher class presentation and student group experiments. Marine baby is a kind of swelling after absorbing toys, widely used in fish tank or vase packing, marine baby is the main component of sodium polyacrylate, good water absorption, color rich and colorful, about ten times the volume after absorbing water, and water Posterior soft and easy to break. The application of marine baby to the design of the original battery experiment not only is novel and unique, but also experimental operation is simple and obvious, and the phenomenon is obvious. Second, the micro-battery experimental design
