Question

which of the following lists the types of mixtures in order of increasing particle size?
○ solution < colloid < suspension
○ suspension < solution < colloid
○ suspension < colloid < solution
○ (suspension = colloid) < solution
○ solution < (suspension = colloid)

Explanation:

Solutions have the smallest particles (typically <1 nm), colloids have intermediate-sized particles (1-1000 nm), and suspensions have the largest particles (>1000 nm). So the order from smallest to largest particle size is solution < colloid < suspension.

Answer:

solution < colloid < suspension
