That statement is incorrect. The formation of oil globules in a water and oil mixture when shaken is due to surface tension and the difference in polarity between oil and water, not an acidic interaction.

Here's a breakdown:

* Oil and Water are Immiscible: Oil and water are immiscible because they have different polarities. Water is a polar molecule, meaning it has a positive and negative end. Oil, on the other hand, is nonpolar, with no distinct positive or negative ends. This difference in polarity prevents them from mixing.

* Surface Tension: Water molecules have a strong attraction to each other due to hydrogen bonding. This creates a surface tension at the water's surface. When oil is added, the surface tension of the water forces the oil molecules to clump together, forming globules.

* Shaking Increases Surface Area: Shaking the mixture increases the surface area between the oil and water, allowing more oil molecules to come into contact with water. This, in turn, results in the formation of smaller oil globules.

Acidity is not a factor in the formation of oil globules in a water and oil mixture.
