10. a) Investigate and briefly report on the cleansing action of soap from the perspective of
micelles. hi Comnare and contrast solutions colloida
Solution
The soap molecule has a hydrophilic polar head and a hydrophobic non-polar hydrocarbon tail.
The hydrophilic polar head binds with water and the hydrophobic non-polar hydrocarbon tail
binds with grease, oil and other non-polar dirt. When oil, grease or dirt is mixed with the soap
water, the soap molecules arrange themselves to form tiny clusters called micelles. The
hydrophilic part of the soap molecules moves towards the water and the hydrophobic part point
outwards and form outer surface of the micelle. The hydrophobic parts moves towards oil, grease
or non-polar dirt and form a trap, where, the hydrophobic dirt is in the center and can\'t come
outside, preventing the contact with water. Thus the micelle is soluble in water with the
hydrophobic dirt is in the center and when rinsing the soapy water, the hydrophobic dirt also
goes along with it.
