What makes a gelatin a colloid mixtures?
Gelatin sets on cooling because the hot aqueous mixture of gelatin coagulates as it cools and the whole mass, including the liquid, sets to an extremely viscous body known as a gel, a colloid in which the dispersing medium is a solid and the dispersed phase is a liquid.

- A suspension is cloudy and heterogeneous.
- A colloid is intermediate between a solution and a suspension.
