中文名称；软水

外文名称；soft water

化学式；H2O

沸点；100 ℃

定义；水中含有钙离子和镁离子的数值

特点；不易与肥皂产生皂垢

'''软水'''（soft water）指的是不含或含较少可溶性钙、[[镁化合物]]的水。软水不易与肥皂产生皂垢，而硬水相反。天然软水一般指江水、河水、湖（淡水湖）水。

经软化处理的硬水指钙盐和镁盐含量降为 1.0～50 毫克/升后得到的软化水。虽然煮沸就可以将暂时硬水变为软水，但在[[工业]]上若采用此法来处理大量用水，则是极不经济的。<ref>[https://www.zhihu.com/question/26631721 直饮水、净水、软水的区别是什么? ], 知乎 , 2016年4月7日</ref>
