In a bottle of salad dressing, the vinegar separates from the oil because Water molecules form H - bonds with each other and exclude fat.
What causes water and oil not to mix?
The reason why water and oil do not mix is due to the fact that water is a polar molecule. But for oil and fats they are not polar molecules because they do not have polar parts. In order for them to be able to dissolve in water they may have to break some of the water in the hydrogen bond.
Hence we can say that in a bottle of salad dressing, the vinegar separates from the oil because Water molecules form H - bonds with each other and exclude fat.
