When fatty acids are added to an aqueous solution, they can either sit on top of the solution, forming a ________ or form spherical ________ throughout the solution.

Question

Quizplus · Accepted Answer

When fatty acids are added to an aqueous solution, they can form a monolayer on top of the solution or form spherical micelles throughout the solution. A monolayer is formed when the fatty acid molecules arrange themselves in a single layer on the surface of the water. On the other hand, micelles are formed when the fatty acid molecules cluster together in a spherical shape to form a water-insoluble core, surrounded by a water-soluble shell. Therefore, the best choice is A, where a monolayer is formed on top of the solution or spherical micelles are formed throughout the solution.
