Pure Substances VS. Mixtures

1. Mixtures

1.1. Heterogeneous vs Homogeneous

1.1.1. Heterogeneous: You can see different particles

1.1.2. Heterogeneous: not evenly based particles

1.1.3. Homogeneous: Evenly balanced particles (solution)

1.1.4. Homogeneous: Example: iced tea, coffee, as well as blood plasma

1.2. Separating mixtures

1.2.1. You can apply water to some mixtures to separate

1.2.2. You can apply heat to some mixtures to separate them

1.2.3. You can use a filter and a funnel to separate mixtures from water.

1.3. Solutions

1.3.1. Evenly balanced particles

1.3.2. Can't see the different particles

1.3.3. Solute and solvent

1.3.4. Looks like one substance

2. Pure Substances

2.1. elements

2.2. constant composition

2.3. water is example because there are equal amounts of even molecules

2.4. compounds are also pure substances

2.5. Alloys and other solutions may be considered pure

2.6. Examples of pure substances: gold, water, brass, salt, etc.
