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.
Soft water produces more lather when soap is added compared to hard water. Soft water has fewer minerals, such as calcium and magnesium, which can react with soap to form a scum that reduces lather production.
No. Hard water is water with high amounts of dissolved calcium and magnesium.
Hard water is produced when water passes through rocks and soil that contain high levels of minerals such as calcium and magnesium. These minerals dissolve into the water, making it "hard" by causing issues such as soap scum buildup and reduced lathering of soaps and detergents.
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.
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.
There are two main types of bath water. These types of water can be either hard water or soft water.
No. There is different types of hard water.There is slightly hard, moderately hard, hard and very hard water.And as for soft water it has to have less than a grain of calcium or magnesium. Hard water isn't as useful as soft 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.
the difference is that soft water contains no dissolved minerals.the hard water contains dissolved minerals

how many types hard disk drives
soaps use natural fats that can get removed from solution by hard water salts, like magnesium and calcium. Detergents use enzymes that attack specific stains, and can clean, even in water containing hard water salts.
There are two types of Hard disk. 1:Sea gate disk 2:SATA Hard disk
there are two types of partitions in the hard disk is primary and logical.
Hard water refers to water that has very high mineral content, which affects its behavior in pipes and its affect on other chemicals like soap, where it often causes the formation of soap scum. Hard water also has a tendency to form deposits in pipes. Normally you wouldn't WANT to make water become hard, and there are systems for trying to reduce the "hardness" of water in the pipes of your home.
Both types of water are used for drinking. Water from wells is usually "hard" water; water from lakes or rivers is usually "soft" water (but this may not be true in all cases; rivers or lakes that are fed primarily by springs will usually be hard-ish water compared to rivers or lakes that are formed primarily from rainfall or snow melt runoff). There's nothing inherently wrong with drinking hard water; in fact it may be slightly healthier than soft water, because it contains calcium (and often iron). However, if you're used to soft water, hard water will taste funny to you and vice versa.
