Final answer:
A suspension is a heterogeneous mixture in which particles settle out, while a solution is a homogeneous mixture in which no settling occurs. Suspensions are cloudy and visible, while solutions are transparent. Colloids have properties between suspensions and solutions.
Step-by-step explanation:
A suspension is a heterogeneous mixture composed of relatively large particles that settle out after mixing, while a solution is a homogeneous mixture in which no settling occurs and the dissolved species are molecules or ions. Suspensions are cloudy and visible, whereas solutions are transparent. Colloids are mixtures that exhibit properties intermediate between suspensions and solutions.
