摘要
尝试利用高吸水树脂对"酸碱中和反应、碳酸钠和碳酸氢钠分别与稀盐酸反应、探究分子运动现象"这3个实验进行创新改进,充分利用了高吸水树脂特殊的结构作用,使3个实验的现象更加显著。改进实验操作简便,高效简洁,值得推广到一线化学课堂的演示实验或学生分组实验。
This paper used super absorbent resin to improve the design of three experiments "an acid-base reaction, sodium carbonate and sodium bicarbonate reacting with dilute hydrochloric acid respectively, exploring molecular motion phenomena". The super absorbent resin, with a special structure, made experimental phenomena more obvious. The improved experiment was easy to operate and with high efficiency, and was worth extending to the demonstration experiment and the group experiment.
