what is micelles ? why does it from when shop is added to water ? will a micelle be formed in other solvemts such as ethanol also ? state briefly how the formation of micelles help to clean the clothes having oily spots
Answers
Answer:
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.
A micelle or micella is an aggregate of surfactant molecules dispersed in a liquid colloid. A typical micelle in aqueous solution forms an aggregate with the hydrophilic "head" regions in contact with surrounding solvent, sequestering the hydrophobic single-tail regions in the micelle centre.

No, micelle formation does not take place in ethanol because the alkyl chain of soap becomes soluble in alcohol.
