在NaBr溶液中滴加进氯水,能看到溶液变黄。说明Cl_2+2NaBr=Br_2+2NaCl反应发生了。为了增大反应现象的明显程度,提出对高中教材这一实验的改进。
Chlorinated water was added dropwise to the NaBr solution, and the solution turned yellow. It shows that Cl_2+2NaBr=Br_2+2NaCl reaction occurred. In order to increase the apparent degree of the reaction, an improvement was proposed for the experiment of high school textbooks.
