Question

Explain why:
1)Micelles are not formed when soap is added to ethanol.
2)Soap does not form lather in hard water .​

Answer 1

(1)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. ... For soaps to form micelles it is necessary that the hydrophobic end sticks to the dirt (dirt is generally organic in nature).

(2)Soap do not lather with hard water because the hard water contains too much of soluble salts of magnesium and calcium. ... But soap forms lather with soft water as they don't have soluble salts in them
