Types of Hardness of Water
There are two categories of hardness of water:
- Temporary Hardness
- Permanent Hardness
Temporary Hardness of Water
Water becomes instantly hard due to the carbonates of calcium and magnesium present. In this situation, boiling the water will remove the hardness.
When water is boiled, the soluble salts of magnesium(HCO3)2 are changed into the insoluble magnesium(OH)2, this forms precipitates and is eliminated. We obtain soft water as a result of filtration.
Permanent Hardness of Water
Since boiling cannot eliminate the soluble compounds of calcium and magnesium from water, the presence of these salts in the form of chlorides and sulfides is referred to as persistent hardness.
By using washing soda to treat the water, we may get rid of this hardness. When washing soda combined with calcium magnesium sulfide and chloride salts, insoluble carbonates are created, turning hard water into soft water.
Hardness of Water: Temporary and Permanent Hardness
Hardness of Water is caused due to the presence of soluble bicarbonates, chlorides, and sulfates of calcium and magnesium. Hard water is water that does not lather when soap is added. There might be some small health benefits in drinking hard water. It can present severe problems in factories where water hardness is monitored to prevent expensive breakdowns in boilers, cooling towers, and other water-handling equipment.
In this article, we will learn, what is hardness of water, the types of hardness, how to remove it along with the disadvantages and harmful effects of the hardness of water.
