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.
Wat salt is responsible for temporary and permanent hardness of water?
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
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.
What are the types of hard 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.
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.
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 can you destroy permanent hardness of water due to sulphates of metals?
zeolites

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.

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 salts can cause hardness of water?
calcium and magnesium
What method remove both temporary and permanent hardness of water?
Boiling method
How is potassium palmitate used in the determination of water hardness?
Sodium palmitate produce a permanent lather with hard water..
