Study Notes

Suspensions

Composed of large particles that do not remain mixed and create a heterogeneous mixture.
Examples include Italian dressing, dusty air, asthma inhalers, and snow globes.
Display Tyndall effect: particles scatter or block light due to their size.
Can be separated through filtration or settling.
Notable for temporary mixtures where particles may settle over time.

Colloids

Consist of medium-sized particles that are larger than those in solutions but smaller than those in suspensions.
Homogeneous in nature; individual particles are not visible.
Examples include processed milk, Jell-O, foggy air, jelly, and whipped cream.
Particles remain mixed and cannot be filtered; exhibit Tyndall effect.
Stay mixed and do not settle over time.

Solutions

Made up of very small particles that create a homogeneous mixture; cannot see individual components.
Soluble and stay mixed like colloids, but do not scatter light.
Examples include cola, lemonade, alloys, anti-freeze, air, and salt water.
Cannot be filtered, as particles are too small to separate.
