Micelles and Biological Membrane

Micelles are the type of lipid molecules that organize themselves in spherical shape in aqueous solutions. The production of the micelle is a reply to the amphipathic behavior of fatty acids. It means that they consist of both hydrophobic regions and hydrophilic regions. In micelles, polar head groups (hydrophilic groups) produce an outer layer associated with water whereas nonpolar tails (hydrophobic groups) are organized in the interior.

Question

Part B: Miscibility of liquids
1.
Place 10 drops of propan-2-ol into each of two DRY semi-micro test tubes.
2.
Add 10 drops of water to one test tube and 10 drops of cyclohexane to the other test tube, shake and observe whether
the two liquids in each test tube are miscible. Record your results then discard the contents of the test tubes into the
organic waste container.
3.
Place 10 drops of water in a clean semi–micro test tube and add 10 drops of cyclohexane to it. Record whether the two
liquids are miscible. If two layers form (i.e. the liquids are immiscible) add a drop of blue food dye to the mixture and
shake, then allow the two layers to reform. Based on your observation, decide whether the food dye is more soluble in
water or cyclohexane and then discard the mixture into the non–halogenated waste container.
Record whether the combinations of liquids shown below are miscible.

In a test tube, dissolve 10 drops of methanol in 3 ml. of water. Oxidize a copper wire spiral by passing it through a Bunsen burner. Plunge the red-hot wire into the alcohol solution several times, cooling the solution under the tap (faucet) so as not to evaporate too much of it. Next, add 1 drop of 0.5% resorcinol solution. Measure 2 ml. of concentrated sulfuric acid (CAUTION!) and pour this carefully down the sides of the test tube containing the mixture. Note the color of the zone intermediate between the acid and the solution. RESULT:

5. EXTRACTION To 1 ml. of bromine water in a test tube add .5ml chloroform or carbon tetrachloride. Note the color of the liquid layers. Which layer is more colored? What do you call such liquids which do not form a homogenous mixture? Can you possibly make them homogenous? How? Transfer the mixture into a separatory funnel and add 2 ml. more of bromine water and add 1 ml. more of chloroform of carbon tetrachlorides then shake to effect proper mixing. Let out the lower layer through the stem of the funnel. Again add another 2 ml. to chloroform or carbon tetrachloride to the aqueous solution in the funnel and shake as before. How does the color of the chloroform or carbon tetrachloride layer compare with the first extract? How do you explain the difference? Is it possible that after several extractions the chloroform layer will become colorless? Why?
