詳細介紹:

水質硬度:

  • 水的硬度是由鈣,鎂離子引起幾乎完全。其它二-和三價金屬具有類似的效果,但通常不存在於足夠高的濃度在飲水造成很多問題。硬度增加肥皂消費洗衣店,並導致大規模的鍋爐。
  • 簡單地計算來改變溶液的顏色來確定硬度濃度所需的滴數。

Hardness:

  • Water hardness is caused almost entirely by calcium and magnesium ion. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers.
  • Simply count the number of drops required to change the solution color to determine hardness concentration.
