why does micelle formation take place when soap is added to water?
Answers
When soap is added to water, micelle formation takes place, this is because the hydrocarbon chains of soap molecules are hydrophobic while the ionic ends are hydrophilic and hence soluble in water.
Micelle will not form in all types of solvents. It will form in such type of solvent where soap is insoluble in that particular solvent.
No, micelle formation does not take place in ethanol because the alkyl chain of soap becomes soluble in alcohol. Micelles can be formed only around suspended molecules of oil in a mixture. Ethanol is a very good solvent and it can even dissolve oil to form a clear solution
Plzzz hit the

the salts which are present in the soap molecules have hydrophobic and hydrophilic ends
so one end pulls or repels against water and the other end just attracts the dirt , as the other end os already pulling the dirt just goes away with water
