前不久，一女子使用网上推荐的"白糖加醋烧开"方法去除保温壶水垢。她将白醋、白糖和水的混合溶液 烧开，倒入保温壶约1分钟后，壶内高温液体突然喷出，导致其面部烫伤。该事件被多家媒体报道，引 发广泛关注。 那么，用白醋和白糖去水垢是否有科学依据？还有哪些所谓的生活"妙招"容易变"险招"？科技日报记者 日前就此采访了北京化工大学化学学院副教授王桂荣。 "从科学原理来看，用白醋除水垢是可行的。"王桂荣说，水垢是难溶于水的碱性物质，主要成分是碳酸 钙和氢氧化镁。白醋含乙酸，又被称为醋酸，属于弱酸。把白醋倒入有水垢的水壶，白醋会和水垢中的 碳酸钙与氢氧化镁发生化学反应，产生可溶于水的醋酸钙和醋酸镁，进而使水垢溶解。 "上述化学反应，通常不会很剧烈，也不会有太大风险。造成女子被烫伤的关键因素是高温。"王桂荣解 释道，女子向保温壶中倒入了烧开的白醋、白糖和水的混合溶液，加速了化学反应速度，导致保温壶内 迅速产生了大量二氧化碳气体。保温壶的密封性较强，二氧化碳气体无法及时扩散，只能在壶内不断积 聚，使壶内气压随之急剧升高。当气压超过壶盖能够承受的极限时，高压气体便会带着壶内的混合物， 从壶嘴喷射而出。 "只要掌握正确的方法，就能 ...
