次氯酸漂白实验是中学化学教学中一个十分重要的经典实验,它以生动的实验现象清楚地证明,能使有色物质褪色的是次氯酸而不是氯气。但是,在利用课本中的实验装置和方法进行实验时,有的教师常常会因为实验装置复杂、氯气量大且容易泄漏造成环境污染等原因,便放弃了实验机会,或用课件替代实验,更不用说让学生动手做课堂实验了。为此,笔 The hypochlorous acid bleaching experiment is a very important classical experiment in chemistry teaching in middle schools. It is clearly demonstrated by vivid experimental phenomena that hypochlorous acid can be used instead of chlorine gas to discolor colored substances. However, when experiments are conducted using experimental devices and methods in textbooks, some teachers often give up experimental opportunities or substitute courseware instead of experiments due to complicated experimental devices, large amounts of chlorine gas, and easy leakage of environmental pollution. Needless to say students are allowed to do classroom experiments. For this, the pen
