在高中化学第一册(1952年出版)P.40.上讲到用电解法制取氯和苛性钠的实验时,倘使照书里的方法去做,在普通设备简陋的学校,做起来不大容易。为了克服这一困难,根据电解食盐的原理,做了一个很简便的而且很经济的电解器,实验结果良好,现在让我们将这种方法作详细的介绍。(一)装置材料:(1)U 形管一个。(2)碳棒两根作电极(可用已经用过的电池,取其中间碳棒)。(5)细铜丝两根.联结电源用。(4)电源:手电筒之干电池四小筒.
In the first high school chemistry (published in 1952) P.40. On the electrolysis of chlorine and caustic soda experiment, if the way to do the book, in the simple and crude school of ordinary equipment, not much to do easy. In order to overcome this difficulty, according to the principle of electrolysis of salt, a very simple and economical electrolyzer was made and the experimental results were good. Now let us introduce this method in detail. (A) device materials: (1) a U-shaped tube. (2) two carbon rods for the electrode (available batteries have been used, whichever is the middle carbon rod). (5) two thin copper wire. Power connection. (4) Power: four small cylinder dry flashlight.
