Question
Chapter 21.4, Problem 24R
To determine
Diagram how soap cleans our hands are to be explained.
Expert Solution & Answer
Answer to Problem 24R
Explanation of Solution
Soap is an excellent cleanser. Soap has an ability to remove oil, which naturally does not mix with skin. Organic part of soap is polar. Its water loving part (hydrophilic) connects with water molecules with ion dipole interaction and hydrogen bonding. Water fearing (hydrophobic) part of soap is nonpolar hydrocarbon chain, connects with each other with dispersion force. Forming structures called micelles. In this carboxylate groups which are negatively charged sphere is present. The micelles ofsoap repel each other and remain dispersed in water.
Conclusion:
Soaps are excellent cleansers, ability to act as an emulsifying agent.
