A filter; filtration
A filter can also identify a Mixture as a Suspension
The particles in Colloids are SMALLER than particles found in Suspensions
The difference is that Colloids don't separate into layers

Answer 2

The filter is used to identify a mixture as a colloid.

Step-by-step explanation:

Colloids are those substances that, being in a liquid, slowly disperses. A colloid is made up of two phases: a dispersing phase and a dispersed phase. By dispersing little by little, the filters are used for their separation, for example, being in a liquid, the colloidal particles are large enough to be blocked by the filter and thus separate them.
