MixturesMixtures

Combinations of different types of matter that can easily be separated from one another.

Page 6: Pure Substances Cannot be broken down into simpler substances and still have the same properties

MixturesMixtures

Homogeneous Mixtures

Look the same throughout.

Include solutions, colloids, and suspensions.

Solutions have one substance that is so small it is“dissolved” in another

substance

Colloids and the Tyndall Effect:Particles are larger in a colloid than in a

solution

A suspension

has particles

that eventually will settle

to the bottom.
