Separating Mixtures using Physical

PropertiesHow can you separate out many

kinds of matter?

Separating Mixtures

USING A MAGNET

Separating MixturesUSING A FILTER & FUNNEL

This only works if the solid Is NOT dissolved by the solvent, and you have a suspension. After filtering, you have a precipitate.

Separating MixturesUSING EVAPORATION

Separating MixturesUSING DISTILATION

Separating Mixtures

A separation funnel can be used if the two liquids will not mix. Often used when separating organic material (oil) and aqueous material (water).

USING DENSITY

Can be accelerated using sonication

Separating MixturesUSING CHROMOTOGRAPHY

Separating Mixtures (Combo)

BY DISSOLVING & FILTRATION & EVAPORATION

A mixture of salt and sand can be separated by dissolving the salt in water, then using filtration separate the sand from the aqueous salt layer. Then evaporate the water to obtain solid salt again.

Separating Mixtures (Combo)

BY DISSOLVING & DENSITY

A mixture of salt, sand, and blue plastic beads can be separated by dissolving the salt in water, then using density to separate into three layers.

Conservation of MassMATTER CANNOT BE CREATED OR DESTROYED, ONLY CHANGE FORMS

If you add vinegar (10 g) to milk (100g) and it thickens,how much matter do you have?

You will observe and analyze the separation of mixtures based on physical properties of matter.

Separating Mixtures – Lab Details

ITEMS: GOGGLES, funnel, filter paper, filter cone, magnet, volumetric cylinder, water (from sinks), evaporating dish, and unknown substance mixture.

ODesign step-by-step procedures to separate the mixture. Include a flow chart.

ODescribe how each substance was able to keep its own physical properties when it was mixed with another substance. (key words: density, magnetism, solubility)

OHow do you know that the mixture of substances is not a chemical combination?
