1. A micelle or micella is an aggregate of surfactant molecules dispersed in a liquid, forming a colloidal suspension. A typical micelle in water forms an aggregate with the hydrophilic "head" regions in contact with surrounding solvent, sequestering the hydrophobic single-tail .
2. 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. ... It will form in such type of solvent where soap is insoluble in that particular solvent
3. No, micelle formation does not take place in ethanol because the alkyl chain of soap becomes soluble in alcohol. Hence, micelle formation takes place in water as solvent not in ethanol

Answer 2

Answer:

HEY DEAR.!!

MICELLES : when molecular ions in soaps and detergents aggregate, they form micelles.

soap molecules have two ends, hydrocarbons ends, water repellent where as ionic part which is water loving. when soap is added to water, the hydrophobic 'tail' of soap will lot dissolve in water and soap will align along the surface of water with ionic ends in water and hydrocarbons 'tail' out of water by forming cluster of molecules called micelle.

No, micelle will not be formed in ethanol, as soap will dissolve in ethanol. micelles trap dirt, grease, oily spots, etc. which is washed away by water or the oily dirt is collected at the centre l'd miclles which forms as emulsion in water and in rinsing the water washes away dirt attached to them.

hope it helps dear
