Which statement best describes a heterogeneous mixture in relation to a solution?
A
A heterogeneous mixture is a solution because its particles are dissolved at the molecular level.
B
A heterogeneous mixture is a solution because it consists of two or more substances.
C
A heterogeneous mixture is a solution because it is always transparent.
D
A heterogeneous mixture is not a solution because its components are not uniformly distributed.

1
Understand the definition of a solution: A solution is a homogeneous mixture where the solute particles are dissolved uniformly at the molecular or ionic level throughout the solvent.
Recognize that a heterogeneous mixture consists of two or more substances that are not uniformly distributed, meaning you can often see distinct phases or particles.
Compare the characteristics: Solutions are uniform and transparent, while heterogeneous mixtures are non-uniform and may be cloudy or have visible components.
Analyze each statement in the problem to see if it aligns with the definitions: For example, a heterogeneous mixture cannot be a solution because its components are not uniformly distributed.
Conclude that the correct description is that a heterogeneous mixture is not a solution because its components are not uniformly distributed.
