Abstract From the demonstration experiment of the reaction of sodium and chlorine in the textbook, a unique experimental device was designed and the preparation of sodium iodide was completed in the laboratory. This experiment avoided the hazards of chlorine gas and met the teaching needs. And the feasibility of this experiment was proved by the relevant calculation from thermodynamics.
