摘要
电解熔融NaCl实验具有较高的教学价值，但由于实验要求太高在教学实践中难以实做。因此通过实验研究，指出电解熔融NaCl实验设计要解决产生高温、降低NaCl熔点、选择电极、选择容器、如何取出钠等问题，在此基础上设计电解熔融NaCl并检验金属Na和Cl2的演示实验，该实验易于操作，现象明显，能够为电解的教学提供有效支持。
The experiment of electrolyzing molten NaC1 had high teaching value, but it was difficult to demonstrate in the classroom because of the high demand. This paper pointed out that the experiment design needed to solve some problems, the generation of high temperature, reduc- ing the melting point of NaC1, the selection of electrodes and container, how to take metallic Na out of the system without being oxidized. Based on the research, this paper designed a demon- stration experiment that could test Na and CI2. This experiment was easy to operate and with ob- vious phenomenon, it could effectively support the teaching of electrolysis.
