关于氯水滴加于Br^-、I^-混合液中出现无色时的探索

Search for the Uncolor Reaction of Saturated Chlorine Water with Br-and I-Ion

在无机实验中,将新制饱和氯水滴加于Br、I^-混合液中,将会在CCI_4层中依次出现浅紫红包→紫红色→浅紫红色→无色→淡黄色→金黄色→橙色→橙红色的颜色变化,我们的兴趣就在于新制饱和氯水究竟加到多少量时,即多少滴时会在Br、I^-混合液的CCI_4层中出现无色这一现象,此无色液中究竟存在何种离子。

Adding the saturated chiorine water to the mixtures of Br-ion and I-ion will pro- duce a series of color changes in CCl_4 layers.The uncolor solution present in the mixtures is a quite interesting.We will study the mount of the saturated chiorine water may be required while the uncilor solution appear and prove the ions in the uncolor solution.
