Answer:
Suspensions (heterogeneous solutions) are non-uniform in color and will sometimes look cloudy or murky, like muddy water. You will definitely see particles floating around in a suspended solution.
A suspension is a heterogeneous mixture in which the solute particles do not dissolve, but get suspended throughout the bulk of the solvent, left floating around freely in the medium. The suspended particles are visible under a microscope and will settle over time if left undisturbed.
