Understanding Activated Charcoal as a Gel Colloid

What is activated charcoal classified as?

A. Suspension

B. Elixir

C. Gel

D. Solution

Answer:

The correct classification of activated charcoal is C. Gel.

Activated charcoal is a form of carbon that is processed to have many small pores that increase the surface area available for adsorption or chemical reactions. It is considered a colloid because it does not dissolve in liquid and the particles are dispersed and do not settle.

Specifically, activated charcoal is classified as a gel colloid. This means that it has a semisolid form where the liquid phase is absorbed by the solid carbon particles. The solid carbon particles create a network that traps the liquid, making it an effective adsorbent in various applications.

So, the next time you encounter activated charcoal, remember that it belongs to the category of gel colloid due to its unique properties and structure.
