Question

DISCUSSION 1. Using what you learned about the structures of soap and micelles, explain what would map if soap molecules were mixed into a sample of pure vegetable oil. You may provide an illustration to help support your explanation. 2. Using what you've learned previously about light's interaction with matter, and what you've observed with the Tyndall effect, explain why the sky appears blue. (Hint: read the introduction to this experiment.)

Answer 1

soap molecule is a sodium highes fatty acid. It will have polar hydrocarbon part and polar Hydrocarbon part of the The Salt of a non -coo Na part Soap molecule is hydrophobic. The salt end (-cooo, is hydrophylic. The hydrophobic art (non poder end) will have a natural tendency in attaching to oil (Vegetable oil) drop. This forms the basis of cleansing action of soap (and detergents). In clansing mechanism, soap molecule attach its non polar end towards oil drof which coenists with dirt also and the polar end of the Soup molecule atteaches to water colecule. This will form micelles which are soluble in water and dirt trapped in oil forming micell will be washed away lates. como o Ho 7 the ones sind urco to micell entity. oor oil metod the

The soap molecule with it's non polar (hydrocarbon chain) end attaching to oil drof and it's polar end attaching with water forms micells. So Soap makes Coordination with both oil and water thus forming micelles. Dust particles present in atmosphere of the earth are colloidl. (Size 1- 1000 nm) So the colloidal particles present in air move randomnly in Zig-Zag mannes.

This zigzag movement of colloidal particle is called as Brownian movement. This is one characteristic of colloidal particles and makes light to scatter in all directions. Tyndal effect is also another light scattering property of colloidal particles.Thus the light scattering property of collodal particles ( dust particles in atmosphere are colloidal ) is the cause of sky appearing in blue color when observed from earth.
