Question

which criteria are responsible for deciding whether a heterogeneous mixture is a colloid or a suspension?

Answer 1

The differences, as illustrated by the attached table, are that the particles of a colloid are smaller than those of a suspension, and that the particles do not separate out in a colloid but they do in a suspension. As an extension of the latter property, a colloid cannot be separated by filtration while a suspension can be. The optical properties are useful to make a quick determination. 

Answer 2
