The common methods used to remove permanent hardness of water are ion exchange, lime-soda treatment, and distillation. Ion exchange involves passing hard water through resin beads that exchange calcium and magnesium ions with sodium ions. Lime-soda treatment involves adding lime (calcium hydroxide) and soda ash (sodium carbonate) to precipitate out the calcium and magnesium ions. Distillation involves boiling water to separate it from the minerals causing hardness.

here two type of hardness 1-temporery 2-permanent *temporery hardness-it is also known as carbonate hardness and alkiliny hardness.it is unstable hardness.it is remove by boiling.it is the due presence of carbonate.
What do you mean by hardness of water. how is it classified. mention the disadvantages of using hard water for various purposes?
Hardness of water refers to the concentration of dissolved minerals, particularly calcium and magnesium ions. It is classified as temporary hardness, which can be removed by boiling, and permanent hardness, which requires water softening methods to remove. The disadvantages of using hard water include scale buildup in pipes and appliances, reduced efficiency of soaps and detergents, and potential skin irritation.
Why temporary hardness is removed from water by boiling but permanent hardness is not?
Permanent hardness is hardness (mineral content) that cannot be removed by boiling. It is usually caused by the presence in the water of calcium and magnesium sulphates or chlorides which become more soluble as the temperature rises.
How can you effectively remove hardness from water?
One effective way to remove hardness from water is through a process called ion exchange. This involves passing the water through a resin that exchanges calcium and magnesium ions, which cause hardness, for sodium ions. This results in softened water that is free from hardness minerals.
How can I effectively remove water hardness from my water supply?
To effectively remove water hardness from your water supply, you can use a water softener system. This system works by exchanging calcium and magnesium ions in the water with sodium ions, reducing the hardness. Another option is to use a reverse osmosis system, which can also help remove hardness minerals from the water. It is important to regularly maintain and monitor these systems to ensure they are working effectively.
What method remove both temporary and permanent hardness of water?

Wat salt is responsible for temporary and permanent hardness of water?
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
Is it possible to remove hardness of water by electrolysis?
No, electrolysis does not remove hardness from water. Hardness in water is caused by dissolved minerals such as calcium and magnesium. Electrolysis involves the decomposition of water into its constituent elements, hydrogen and oxygen, and does not address the presence of mineral ions that cause water hardness. Physical methods such as ion exchange or chemical methods like adding a water softener are more effective for removing hardness from water.
What other substance cause by permanent hardness?
Permanent hardness in water is hardness due to the presence of the chlorides, nitrates and sulphates of calcium and magnesium, which will not be precipitated by boiling.
How do you get rid of water hardness?
Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.
What causes permanent hardness of water?
Permanent hardness of water is caused by the presence of dissolved calcium sulfate and magnesium sulfate, which cannot be removed through boiling. These minerals form insoluble compounds that remain in the water even after treatment, leading to permanent hardness.
What are the two form of hardness found in water?
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
How hardness of water can be remove?
Hardness of water can be removed with a water softener. These devices pump the water through salt to remove minerals and other particles.
What salts can cause hardness of water?
calcium and magnesium
