3. Mayonnaise is an emulsion made from oil, water and egg yolks. What type of molecule islikely present in egg yolk to allow the oil and water to mix?4. What do you think happens to the glycerol in the soap making experiment?5. In earlier centuries soap was made by mixing animal fat with ashes (from campfires) Ifyou tested the pH of a mixture of ashes and water do you think it would be acidic orbasic?6. Hopefully most of the excess sodium hydroxide (NaOH) was removed from your soapduring the filtration step because a soap that contains too much base is harmful tothe skin and hair, silk, or wool. A good soap dissolved in water has a pH of between 7and 9.. What method that we used earlier in this class could have been used to check thepH of soapy water made from the soap you synthesized? How would you have done themeasurement?33 Table 1. Emulsion FormationEmulsion has formed(Yes or No)NOes1.
