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.
Permanent hardness of water due to?
Permanent hardness of water is typically caused by the presence of calcium sulfate (CaSO4) and magnesium sulfate (MgSO4) in the water. These minerals do not precipitate out of solution when water is boiled, unlike temporary hardness caused by calcium bicarbonate which can be easily removed by boiling. Permanent hardness can be removed through processes like ion exchange or chemical precipitation.
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.

How is potassium palmitate used in the determination of water hardness?
Sodium palmitate produce a permanent lather with hard 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 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 salts can cause hardness of water?
calcium and magnesium
How can you destroy permanent hardness of water due to sulphates of metals?
zeolites
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.
Permanent hardness of water due to?
Permanent hardness of water is typically caused by the presence of calcium sulfate (CaSO4) and magnesium sulfate (MgSO4) in the water. These minerals do not precipitate out of solution when water is boiled, unlike temporary hardness caused by calcium bicarbonate which can be easily removed by boiling. Permanent hardness can be removed through processes like ion exchange or chemical precipitation.
What method remove both temporary and permanent hardness of water?
Boiling method
Do Calcium bicarbonate salts cause hardness to the water?
Yes. it causes temporary hardness of water, which can be generally removed by boiling water.
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.
How do you measure permanent hardness by EDIT titration?
To measure permanent hardness by EDTA titration, first add a buffer solution to the water sample to maintain a stable pH. Then, titrate with standardized EDTA solution until the color changes indicating the endpoint. The volume of EDTA required to reach the endpoint can be used to calculate the concentration of the ions causing permanent hardness in the water.
