Answer to Question 1

Emulsions are colloidal dispersions of two liquids, fat and water, which are immiscible, meaning that they do not mix. When put together, for example in a salad dressing, they will separate on standing. Emulsifiers are provided to stabilize the emulsion by forming a monomolecular layer around the oil droplets and preventing their coalescence.
