A student calls a mixture a solution only because it has two substances. What is the correct correction?
Answer and explanation
Correct answer: Two substances are not enough; they must mix homogeneously
A solution is a homogeneous mixture, not simply any mixture containing two substances. Its components must be uniformly distributed and form one phase at the relevant scale. Oil and water, for example, contain two substances but form separate layers, so they are not a true solution.
