Multiple Choice
In the classification of matter, is a heterogeneous mixture considered a solution?
A
Yes; heterogeneous mixtures are always solutions because they contain multiple components.
B
Yes; any mixture with more than one phase is a solution.
C
No; a solution is a homogeneous mixture, not a heterogeneous mixture.
D
No; a solution is a pure substance, while a heterogeneous mixture is not.
Verified step by step guidance1
Recall the definition of a solution: a solution is a homogeneous mixture, meaning its composition is uniform throughout and it has only one phase.
Understand that a heterogeneous mixture consists of two or more phases with visibly different components or regions, so its composition is not uniform.
Compare the two: since a solution must be homogeneous and a heterogeneous mixture is not, a heterogeneous mixture cannot be classified as a solution.
Recognize that a solution is not a pure substance; it is a mixture, but specifically a homogeneous one, which distinguishes it from heterogeneous mixtures.
Conclude that the correct classification is that a heterogeneous mixture is not a solution because it lacks the uniformity and single-phase nature required for solutions.
