An emulsion may be prepared by shaking together or blending two liquids that are:
ACrystalline
BImmiscible
CFully miscible
DBoth gaseous
Answer & Solution
Correct answer: B. Immiscible
1. Not every pair of liquids mixes.
2. Ethanol and ethylene glycol are examples of liquids completely miscible with water.
3. An emulsion is prepared from liquids that will not mix in that way.
4. It may be prepared by shaking together or blending two immiscible liquids.
5. Oil and water beaten together form the everyday example.
