Homogeneous and heterogeneous mixtures differ primarily in their composition and appearance.
### Homogeneous Mixtures:
- **Uniform Composition**: In homogeneous mixtures, the composition is consistent throughout. Any part of the mixture will have the same proportion of components as any other part.
- **Single Phase**: They exist in a single phase (solid, liquid, or gas), meaning that the individual components cannot be easily distinguished.
- **Examples**: Common examples of homogeneous mixtures include saltwater, air, and vinegar. In these mixtures, the individual components (salt, water, gases in air, etc.) are evenly distributed.
### Heterogeneous Mixtures:
- **Variable Composition**: Heterogeneous mixtures have a non-uniform composition. Different regions of the mixture may have different proportions of the components.
- **Multiple Phases**: They can consist of multiple phases, and the different materials within the mixture can often be seen and physically separated.
- **Examples**: Examples of heterogeneous mixtures include salad, sand and salt mixture, or oil and water. In these cases, you can usually see the different parts and can often manually separate them.
In summary, the key distinction lies in the uniformity and visibility of the components: homogeneous mixtures are uniform and consistent, while heterogeneous mixtures are variable and can be visually or physically distinguished.
