Why is oil and water forming separate layers not called a true solution?
Answer and explanation
Correct answer: Because they do not mix uniformly
A true solution is homogeneous: its components remain uniformly distributed and separate layers are not visible. Oil and water are both liquids, but they are immiscible under ordinary conditions and separate into layers because they do not mix uniformly. Thus their physical states are not the problem; the lack of uniform mixing is.
