Presentation Transcript

Techniques for Separating Mixtures Chpt 2 Matter
Filtration • separating undissolved solids from liquids
Distillation • separates liquids based on boiling points
Crystallization • heated solution is cooled; purified dissolved particles solidify (ex. rock candy) • https://www.youtube.com/watch?v=cdi6K6QvF3I
Ammonium chloride crystals
Chromatography • separate components of mixture based on solubility or size of molecules
Magnetization • separates based on magnetic properties (ex. iron in cereal, junkyard)
