Which of the following mixture types is characterized by the settling of particles?

a. solution

b. suspension

c. colloid

d. hydrate

The answer is B. Suspension. Suspension mixtures are composed of two or more materials mixed together wherein the solute particles are usually larger than those found in a solution or colloid. In cases of solid-fluid suspension mixtures, the solid solute particles tend to settle at the bottom of the mixture after some time.
