Hardness of water pretains 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.

∙ 11y agoWater hardness basically means that there is a high amount of mineral content, typically calcium sulphates and magnesium sulphates.
Wiki User
∙ 14y agoThe degree of hardness is defined as the number of parts by weight of calcium carbonate hardness per particular number of parts of water, depending upon the unit employed.

What is the relation between hardness and conductivity?
Resistivity R is the inverse of conductivity G, R=1/G.
Is there any relation between HGI and grade of coal?
YES, there is a relation between HGI and coal quality. HGI is the parameter to indicate the hardness or grindability of the coal when it is used in pulverized coal for boiler
Which does not cause hardness of water?
Magnesium sulfate (MgSo4) does not cause hardness of water.
What is the ppm of hardness of dm water?
Water having dissolved mineral hardness of 1 GPG (grain per gallon) or more qualifies it as Hard water according to the Water Quality Association of the United States definition. If you multiply GPG rating by 1.7 you will get the PPM.
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.
What is the relation between hardness and conductivity?
Resistivity R is the inverse of conductivity G, R=1/G.

YES, there is a relation between HGI and coal quality. HGI is the parameter to indicate the hardness or grindability of the coal when it is used in pulverized coal for boiler
What is the water hardness in zip code 89005?
3.4- 5.5 grains per gallon as CaCO3. Here is the watr quality report for Chattanooga TN http://www.amwater.com/files/TN_0000107_TWQ.pdf
Is there any fundamental unit associated with Rockwell Hardness Test?
No, because hardness is not a fundamental quality
Which does not cause hardness of water?
Magnesium sulfate (MgSo4) does not cause 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
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 is the relation between density and hardness?
density has to do with the molecular structure and molecular mass. hardness is the compacting value of the molecules inside the object. PREFFERABLY PLUTONIUN!!
What is the ppm of hardness of dm water?
Water having dissolved mineral hardness of 1 GPG (grain per gallon) or more qualifies it as Hard water according to the Water Quality Association of the United States definition. If you multiply GPG rating by 1.7 you will get the PPM.
How do you estimate hardness of water?
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.
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 do you control the hardness or softness of the water in the aquarium?
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.
