Separating Mixtures

States of Matter

100

This is a state of matter where its molecules are arranged in a regular repeating pattern.

Solid

200

Molecules in this state are very far apart allowing them to go in different directions.

Gas

300

Molecules in this state is slightly loose allowing them to move and flow. They take the shape of their container.

Liquid

400

Describe the phase change that takes place during evaporation

liquid to gas

500

What factor causes the change in states of matter?

HEAT / TEMPERATURE

Types of Mixtures

100

This type of mixture is the combination of two or more substances where the mixture looks uniform (the same throughout).

(Homogeneous Mixture)

200

This is a type of mixture in which the composition is not uniform throughout the mixture. The components do not mix and can easily be separated.

HETEROGENEOUS MIXTURE

300

This is a type of homogeneous mixture where a solid is dissolved in a liquid.

Solution

400

A heterogeneous mixture where components do not mix and separates in time. (Italian Dressing)

SUSPENSION

500

This is a homogeneous mixture has medium sized particles. Particles are larger than those in a solution but smaller than those in a suspension.

Colloid

Properties of Mixtures

100

Two parts to a solution

Solute & Solvent

200

Most common solvent  (does the dissolving)

Water

300

This is the property of a substance to be dissolved in a solvent.

Solubility

400

What property of a material or substance determines its ability to float or sink.

Density

500

List 3 physical properties that can be used to help identify a susbstance

color, particle size, magnetic, able to dissolve, can evaporate, etc.

Separation Techniques

100

Used to Separate iron from black sand

Magnetism 

200

Separating mixtures based on particle size

Filtration

300

Used to remove a solvent from a solution, leaving behind the solute

Evaporation

400

Physical property that separates mixtures into layers

Density

500

Distillation uses this physical property to separate a mixture

boiling point

Separation Techniques Part 2

100

Tool used to separate a mixture with different sized particles

filter, sieve, strainer

200

This would be an easy way to separate a mixture of salt and pepper

floatation or dissolving

300

Separation Technique used to separate two different liquids

Distillation

400

This method of separating solutions is used for things such as the coloured parts of ink

chromatography

500

Distillation uses these 2 changes of state to separate solutions

evaporation and condensation
