Separation of Mixtures

What do you know about mixtures? Mechanical mixture – has two or more different parts can be seen with the unaided eye Suspensions – a liquid or gas mixture with visible layers of solids or liquids within it Solution – a mixture that appears to be one substance (you cannot see the different parts, even with a microscope)

Mixtures in terms of the Particle Model of Matter Mixtures have two or more types of ______________________________ The particles can be separated ________________ or _______________

Physical Separation of Mixtures Are used when you __________ see the different layers of a mixture:

Filtration

Magnetic Separation

Evaporation Many _______________ mixtures are water- based. To separate them, you need to ________________ the water.

Condensation

Chemical separation of mixtures Used when you ___________ tell the difference between the different layers of a mixture Condensation* - this can also be a chemical separation method if ____________________________ are added to the mixture to remove a type of particle via condensation Crystallization – when you ___________ off all liquids from a mixture in a special way that leaves behind crystal particles

Crystallization
