Pure Substances and Mixtures

What's the difference?

Homogeneous mixtures

... are the same everywhere in the glass. There is no difference from one are to the next. We also call homogeneous mixtures solutions.

Heterogenous mixtures

... you can easily see the different parts, and they can be easily separated.
