Alkali-earth metals Calcium and Magnesium as they are capable to form and precipitate as carbonates when heated, or with natural soap when used in washing with tap water.
Hardness testers look for elements such as metals, and iron in your water. Other elements that it also searches for are nickle and coppers. These can be detrimental to your health if consumed in large quantities.
Magnesium sulfate (MgSo4) does not cause hardness of water.
Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
None are. The elements are not decomposed: the water is. The elements released by the reaction are hydrogen and oxygen.
Hardness of water pertains to the concentration of minerals and other trace elements in your local water supply. Well water-such in my area is "very hard"-meaning it contains a large amount of iron and other minerals-when boiled down in a pot of the water on your stove-it will leave a deposit on the pan once the water has boiled away. A water softener helps filter out these particles.
The water supplier can provide you the details on hardness level if you are on municipal water systems, If you are using private water then you can get tested in laboratories. You can even measure it with water hardness testing kits which you need to purchase.
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.
There are two ways to help control water hardness: use a packaged water softener or use a mechanical water softening unit. Packaged water softeners are chemicals that help control water hardness.
Yes. it causes temporary hardness of water, which can be generally removed by boiling water.
Hardness of water can be removed with a water softener. These devices pump the water through salt to remove minerals and other particles.
