3.填空题(共1题)

5.
天然水里一般含有Ca2、Mg2等多种离子。人们把含有较多量Ca2、Mg2的水叫做硬水,含有较少量或不含Ca2、Mg2的水叫做软水;降低水中Ca2、Mg2含量的过程叫做硬水软化。如果硬度太高(含Ca2、Mg2的浓度太大)会给生产、生活带来很多不利,因此硬水的软化是水处理的重要方面之一。
离子交换法常用于工业锅炉用水的软化。离子交换剂多种多样,磺化煤(NaR)就是一种阳离子交换剂。
(1)写出用磺化煤软化含Ca2、Mg2浓度较高的硬水的化学方程式____________________
(2)用药剂软化法软化过的水总是含有一定浓度的Ca2、Mg2,其原因是_______________
(3)参考烧水后的锅或壶中结有水垢的现象分析说明,如果用硬度太高的水作锅炉用水,主要的不利因素是________________________________________________________________
