Permanent Hardness of Water

Permanent hardness of water is caused due to the presence of sulfates and chlorides of calcium and magnesium such as CaCl2 , MgCl2 , CaSO4 , MgSO4 in water. When we boil the water to eliminate these sulfates and chlorides we can see a white coating on the utensils due to these salts or compounds steadiness. Since boiling can not remove permanent hardness, we have to use some chemical methods for it.

Methods to Remove Permanent Hardness of Water

Water is a crucial part of our lives. It is enriched with minerals that are important for our good health. Permanent Hardness of water is not only a theory but also a real-life problem we deal with every day in our lives. Knowledge of this concept helps the students relate the chemistry concepts to real-life problems and is also important for many exams like JEE and NEET. While temporary hardness is easy to eliminate by boiling, permanent hardness is not, so we have to use some chemical methods in this case. In this article, we will discuss in detail the methods of removing the permanent hardness of water, along with a few topics related to it.

What is Hardness of Water?

The Hardness of water is a measure of the total concentration of soluble minerals such as calcium and magnesium ions including their bicarbonates, sulfates, and chlorides. The hardness of water is also caused by the presence of iron, aluminum, and manganese ions. The geographical location is also responsible for the richness of minerals. The hardness of water is determined by the milligrams per liter (mg/L) and is reported in parts-per-million (ppm) units....

Conclusion

Water is naturally enriched with minerals that are essential for our good health. Hardness of water are of two types – temporary and permanent. Temporary hardness is easy to deal with but permanent hardness isn’t. It is because of the chlorides and sulfates of magnesium and calcium minerals. Hard water is not useful for industries, for laundry works, and also not in our daily life. So, to get rid of permanent hardness of water we use several methods such as Calgon’s method, ion-exchange method, Gan’s permutit method etc. This knowledge of removing hardness and softening water becomes a practical knowledge, as it helps in improving water quality for household uses....
