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.
How do you make permanent hard water soft?
Hard water is the one that does not lather with soap. Permanent hard water can be converted to soft water by adding sodium carbonate (Na2CO3), or calgon or zeolite.
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 minerals are in hard and soft water?
Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
How is potassium palmitate used in the determination of water hardness?
Sodium palmitate produce a permanent lather with hard water..

What is the scum that on the surface of boiling hard water?
The scum on the surface of boiling hard water is usually a buildup of mineral deposits, such as calcium and magnesium. These minerals are present in high quantities in hard water and can form a layer of scum when the water is boiled, especially if there are impurities present.
How do you do soft water from hard water?
Water is a universal solvent and there are two types of water i.e hard water and soft water. Soft water is the water that easily lather with soap while hard water does not lather with soap and is also of two type i.e temporary and permanent.
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.
What is the ice-to-water ratio of hard ice?
The ice-to-water ratio of hard ice is 1:0, meaning there is no water present in hard ice as it is solely composed of frozen water molecules.
What is meant by permanent hard water?
Water containing salts of calcium and magnesium as chlorides, sulfates, nitates - impossible to delete by boiling.
When zeolite is treated with hard water sodium ions are exchanged by?
calcium ions present in the hard water, leading to the formation of calcium zeolite.
Which is the most common storage devices of present day micro computer?
hard disk
