Bro this is too simple.

Soaps contains two ends with having different properties.

They are sodium and potassium salt of long chain carboxylic acid they belong to group called COONa.

Soap contain two ends one is hydrophobic which is repealed by water and attracted by dirt and other is hydrophilic which is attracted by water.

When we dissolve a cloth in soap solution hydrophobic tail moves towards the dirt as it is attracted by dirt. Other end which is ionic end remains dissolved in water as it is soluble in water.

When there is a formation of cluster around dirt particle which contains hydrophobic tail and hydrophilic head is called micelles. Dirt remains at centre of the micelles.

When we shake cloth this dirt particles get pulled by micelles at the surface they remain in water due to ion - ion repulsion which allows them to remain in water. Thus the cloth gets cleaned.

Soaps do not show there reaction or there cleaning action in hard water because hard water contains magnesium and potassium salts which react with sodium to form scum this scum is insoluble in water and turns into precipitate and large amount of soap gets wasted due to which we made another alternation that are :-

Detergents are made amonium or sulphonate

salt which do not react with magnesium and calcium due to which the dirt gets cleaned so detergents work well in hard water rather than soap.

If we have to try to find out whether the water is hard or soft we can use soap to determine that.

Hope this answer is helpful lavish if you think this much is not enough I know more I will edit the answer and rewrite.
