Slide1

Separating Mixtures

August 31Slide2

How do you separate?

How can you separate mixtures?Slide3

Separating

Separating is based on the difference in

physical properties

of the substances…

Think about how you would separate a bag of m&ms

Some mixtures are easier to separate than othersSlide4

What would you rather separate?Slide5

Filtration

Filtration

: technique that uses a porous barrier to

separate a solid from a liquid

Heterogeneous mixtures (sand & water)Slide6

Distillation

Distillation

:

separation technique that is based on

differences in the boiling points

of the substances involved

Homogeneous mixtures (most

)

2 liquidsWhen precisely controlled, distillation can separate substances having boiling points that differ by only a few degreesSlide7
Slide8

Crystallization/Boiling

Crystallization

:

separation technique that results in the

formation of pure solid particles from a solution

containing the dissolved

substance

You boil out the liquid and are left with the solid crystals

Salt water Slide9
Slide10

Chromatography

Chromatography

:

technique that separates the components of a mixture (called the

mobile phase

) on the basis of

the tendency of each to travel

or be drawn across the surface of another material

(called the stationary phase). Example-InkDifferent masses travel different distances!Slide11
Slide12
Slide13

Reflection

Could you separate the colors in black pen ink? How could you do this and what separation technique would you use?Slide14
