常用的演示水电解的实验装置是霍夫曼电解器。这一演示装置只适用于30—40人的小教室,在大教室中不易看清。我们用有机玻璃制成的电解器,并用投影装置进行演示,在二百人的大教室中,不论是电解过程中产生的小气泡,和电解生成的氢气和氧气的体积比都看得十分清楚。一、水的电解器的制作图中所示的是电解器的前视图,主要由有机玻璃做成。
The commonly used experimental apparatus for demonstrating water electrolysis is the Huffman electrolyzer. This demonstration device is only suitable for small classrooms of 30-40 people and is not easy to see in large classrooms. We used an electrolyzer made of plexiglass and demonstrated it with a projection device. In the large classroom of 200 people, both the small bubbles generated in the electrolytic process and the volumetric ratio of hydrogen and oxygen generated by electrolysis were clearly seen. . First, the production of water electrolyzer The figure shows a front view of the electrolyzer, mainly made of plexiglass.
