Hard water contains calcium and magnesium salts. Therefore, in hard water, soaps get precipitated as calcium and magnesium soaps which being insoluble stick to the clothes as gummy mass.

Can you use soaps and synthetic detergents to check the hardness of water?

Yes, you can use soaps and synthetic detergents to check the hardness of water. Hard water forms insoluble scum when mixed with soap, while soft water produces lather easily. If soap forms scum rather than lather, the water is likely hard.


Detergents differ from soaps in that?

Detergents are synthetic surfactants while soaps are made from natural fats and oils. Detergents are more effective in hard water compared to soaps. Detergents do not form scum in hard water like soaps do.


Why are soaps less effective in hard water?

Soaps are sodium or potassium salts of long-chain fatty acids. Hard water contains calcium and magnesium ions. When soaps are dissolved in hard water, these ions displace sodium or potassium from their salts and form insoluble calcium or magnesium salts of fatty acids. These insoluble salts separate as scum. This is the reason why soaps do not work in hard water.


Is detergent similar to soap and can be used in hard water?

Detergents are also called soap less soaps becoz though they act likea soap in having the cleansing properties, they do not contain the usual soaps like sodium starate. detergents are better cleansing agents than soaps because they donot form insoulble calcium and magnesium salts with hard water, and hance can be used for washing even with hard water.


Why are detergents called soapless soaps?

Detergents are called soapless soaps because they are synthetic cleaning agents that work like soap but do not contain actual soap molecules. Instead, they contain surfactants that help to remove dirt and oil from surfaces. These surfactants are effective in both hard and soft water, unlike traditional soaps which can react with minerals in hard water and form soap scum.

Explain that Every detergent are soap but soap are not detergent?

Chemically Detergents are the salts of long chain sulphonic acids and soaps are the salts of long chain fatty acids, both work in normal water but in hard water only detergent works , so detergents may work as soaps but soaps do not work as detergents.

Advantage of soaps over synthetic detergents?

Soaps and detergents act differently in hard water and soft water respectively..over use of detergents causes water pollution wich can be avoided by using soaps...........wich causes much less pollution.

Why do soaps and detergents have different effects in different types of water?

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.

What are the advantages of soap over detergent?

The advantages of synthetic detergents over soaps are :Synthetic detergents can be used even in case of hard water whereas soaps fail to do so. Unlike soaps, detergents do not form insoluble calcium and magnesium salts in hard water. They give lather in hard water also.Synthetic detergents can be used in the acidic medium while soaps fail to do so because of their hydrolysis to free acids.Synthetic detergents are soluble in water and hence form more lather than soaps.Synthetic detergents have a better cleansing action than soaps.Detergents do not cause irritation to the skin while soaps have this problem.


What are the advantages and disadvantages of soaps and detergents?

Soaps are natural products made from fats and oils, which makes them biodegradable and environmentally friendly. They are effective at removing dirt and oils from surfaces. However, they can react with hard water to form scum, reducing their cleaning effectiveness. Detergents, on the other hand, are synthetic compounds that are more effective in hard water and are less likely to leave residue. However, they are not as environmentally friendly as soaps and may contain harmful chemicals.

Does the hard water have a greater emulsifying power than soap or deterget yes or no?

The question should be (I guess)..."Which would have a greater emulsifying power in 'hard' water, soaps or detergents?". The answer to that question is certainly the detergent. (Further, fyi, shampoos are great emulsifiers in hard water compared with the two.)*Please see molecular structures of soaps and detergents to understand how and why detergents emulsify more than soaps.
