In general chemistry, a solution is best described as what kind of mixture?
A
A heterogeneous mixture
B
A colloid
C
A pure substance
D
A homogeneous mixture
Verified step by step guidance1
Understand the definitions of different types of mixtures and substances: a heterogeneous mixture has visibly different components, a colloid has particles dispersed but not dissolved, a pure substance has a fixed composition, and a homogeneous mixture has uniform composition throughout.
Recall that a solution is a type of mixture where the solute is completely dissolved in the solvent, resulting in a uniform composition at the molecular level.
Recognize that because the components of a solution are evenly distributed and indistinguishable, it fits the definition of a homogeneous mixture.
Eliminate other options: it is not heterogeneous because it looks uniform, not a colloid because particles are dissolved, and not a pure substance because it contains more than one component.
Conclude that the best description of a solution is a homogeneous mixture.
