Methods to Remove Temporary Hardness of Water
The methods to remove temporary hardness of water are:
- Clarks Method
- Boiling Method
By Clarks Method
The reagent used by Clark is calcium hydroxide. By changing bicarbonates into carbonate, it takes off the hardness of the water.
Reaction: Ca(OH)2 + Ca(HCO3)2 → 2CaCO3↓ + 2H2O
By Boiling
Filter is used to eliminate insoluble carbonates that are created from soluble bicarbonates.
Reactions: Ca(HCO3)2 → ΔCalo3↓ + H2O + CO2
⇒ Mg(HCO3)2 → ΔMgCO3↓ + H2O + CO2
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.
