漂白水，为什么能让衣服变白？

Clothes get color from dye molecules. 衣服的颜色来自色素分子。 Bleach breaks those molecules apart. 漂白剂把色素分子拆解开。 The broken molecules lose their color. 拆开后的分子就没了颜色。 White cloth looks bright again. 白布又变得亮白如新。 Bleach is strong, so use it carefully. 漂白水很厉害，要小心使用。 It can also fade other colors. 它还会把别的颜色漂淡。 Never mix bleach with vinegar. 漂白水千万别和醋混在一起。
