A day, when I pour water to drink, suddenly discovery has below jug for nothing sedimentary, of the very hard, how to do do do not drop. Asked mom ability knows, this is furring, keep clear of very hard. I go again on the net search what is OK and cleared furring, the result is vinegar, for test and verify this statement is correct, I want to do a test.
一天，我倒水喝的时候，忽然发现水壶底下有一层白白的沉淀物，硬邦邦的，怎么弄都弄不掉。问了妈妈才知道，这是水垢，很难清除。我又去网上搜什么可以清除水垢，结果是醋，为了验证这个说法是否正确，我想做个实验。
An a cup of a bottle of the jug that I prepare to have furring, white vinegar, water, chopstick and a dishcloth, begin to do a test. It is certain that I will be entered in jug first proportional white vinegar and water; Reoccupy chopstick it two mix are even; Write a composition next jug electrify, press switch, heat water, quiet place arrives two hours; Pour water finally, brush jug with dishcloth next, look brand-new below jug, particularly clean. White before vinegar is true can purify furring!
我准备好一个有水垢的水壶、一瓶白醋、一杯水、一根筷子和一块抹布，开始做实验了。我先将水壶里倒入一定比例的白醋和水；再用筷子将它俩搅拌均匀；然后将水壶通电，并按下开关，将水烧开，静置一到两个小时；最后把水倒掉，用抹布擦一擦水壶底下，水壶底下焕然一新，特别干净。原来白醋真的能去除水垢啊！
Is this why? Original, have in the tap water that we boil at ordinary times a few mineral, calcium carbonate and carbonic acid magnesium can arise when heating water, the time that burns water is much, calcium carbonate and the amount with magnesian carbonic acid are increasing, lived to come down in crock bottom simply, for nothing hard hard furring appeared. And acetic acid is contained in white vinegar, acetic acid is met and calcium carbonate and carbonic acid magnesium produce chemical reaction, generation but dissolve is mixed at the acetic acid calcium of water acetic acid is magnesian, get rid of thereby furring.
这是为什么呢？原来，我们平时煮的自来水中有少量的矿物质，烧水的时候会产生碳酸钙和碳酸镁，烧水的次数多了，碳酸钙和碳酸镁的数量就越来越多，索性就在壶底住了下来，白白硬硬的水垢就出现了。而白醋中含有醋酸，醋酸会和碳酸钙和碳酸镁产生化学反应，产生可溶于水的醋酸钙和醋酸镁，从而除掉水垢。
I told mother this small clever court, mom is particularly happy.
我把这个小妙招告诉了妈妈，妈妈特别开心。
