摘　　要：首先,通过对氯水体系中存在的化学过程进行全面深入地综合分析,旨在厘清氯水是由多种分子﹑多种离子和多种自由基组成的复杂的氧化还原系统;其次,通过设计6个实验对氯水在不同条件下的漂白作用进行科学探究,并对实验结果给予科学合理的解释;最后,科学地归纳出氯水的漂白作用是一个多种成分协同作用的过程,影响因素很多,但"主角"仍是次氯酸,并对其漂白作用的化学原理给予科学阐释。Firstly, this paper deeply analyzed the chemical process in chlorine water system,aimed to clear the chlorine water was composed of a variety of molecules, ions and free radicals in the complex redox system; secondly, designed six experiments for scientific inquiry on chlorine bleaching effect under different conditions, and gave a reasonable explanation for the experimen tal results; finally, scientifically summed up the bleaching effect of chlorine water was a process of multiple components of synergy with many influence factors, but the ＂hero＂ was still hypo chlorous acid, and gave corresponding scientific explanation.
