Study Notes
Mixtures
- A homogeneous mixture is a uniform mixture where its components are evenly distributed, making it impossible to distinguish the different parts.
- A heterogeneous mixture is a non-uniform mixture where its components are not evenly distributed, making it possible to distinguish the different parts.
Separating Solutions
- Solutions can be separated through various methods, including filtration, distillation, chromatography, and crystallization.
Examples of Mixtures
- An example of a homogeneous mixture is air, which is a mixture of gases, mainly oxygen, nitrogen, and carbon dioxide, that are evenly distributed.
- An example of a heterogeneous mixture is trail mix, which is a mixture of nuts, seeds, and dried fruits that are not evenly distributed.
