实验室制氯水普遍采用的方法是：将氯气直接通入水中至饱和。因为氯气不能迅速溶解于水，大部分气体逸入空气中，所以利用该方法制取氯水存在一些缺点，如：试剂用量大，耗时长，制得氯水浓度小，有毒的氯气大量逸入空气中，污染周围环境等等。另外现行课本中还没有实验直... The commonly used method for making chlorine in the laboratory is to pass chlorine directly into water to saturation. Because chlorine gas can not be dissolved in water quickly, most of the gases escape into the air, so there are some disadvantages in using this method to produce chlorine water, such as: large amount of reagents, long time consumption, low chlorine concentration, large amount of toxic chlorine gas escaped. In the air, pollute the surrounding environment and so on. In addition, there is no experiment directly in the current textbook...
