We often talk about water of different qualities in our daily life and very often we are faced with certain problems caused by hard water.
The total hardness (TH) consists of all calcium (Ca) and magnesium (Mg) salts dissolved in it. Water hardness consists of two types of hardness, carbonate, and non-carbonate.
Carbonate hardness consists of calcium and magnesium bicarbonates Ca(HCO3)2 and Mg(HCO3)2. Non-carbonate hardness consists of all their other salts such as chlorides, nitrates, sulfates, etc.
After washing in hard water, stains from precipitated limescale remain which are very difficult to remove, textiles washed in “hard” water become stiff due to the deposition of limescale on fine textile fibers, and washing in hard water consumes more detergents due to the reaction of detergents with hardness salts and, creation of insoluble soaps – soap scum.
Using soft water can solve all these problems.

What causes permanent hardness of water?
Presence of bicarbonates of chlorides or sulphates of calcium or magnesium in water are the main causes of hardness of water.
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.
Permanent hardness of water due to?
Calcium, magnesium, iron and manganese ions, the first two are the commonest in household water.
What other substances cause permanent hardness?
Temporary hardness of water is due to the presence of calcium hydrogentrioxocarbonate(IV) which decompose on heating.when this water is heated calcium trioxocarbonate(iv) is form as insoluble and this brings the ca+ out of the solution as precipitate.once the ca+ re out of the solution soap can now lather well.

How can you destroy permanent hardness of water due to sulphates of metals?
zeolites
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.

What is the difference between temp hard water and permanent hard water?
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.

Which does not cause hardness of water?
Magnesium sulfate (MgSo4) does not cause hardness of water.
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.
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 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.
