Study Notes
Homogeneous Mixtures
- Mixtures with a uniform composition throughout.
- Examples include air and sugar water.
Heterogeneous Mixtures
- Mixtures with a non-uniform composition.
- Different particles are visible within the mixture.
- Examples include pasta sauce, sand and water, and trail mix.
Filtration
- Separates solids from liquids.
- Relies on differences in the state and size of components.
- A filter with specific pore sizes is used.
- Allows smaller particles to pass through; larger particles are retained.
- Example: separating sand from water.
Evaporation
- Separates fluids or soluble substances from a solution.
- Relies on differences in boiling points.
- Example: drying wet clothes or hair.
Distillation
- Separates liquids based on their boiling points.
- One liquid evaporates, then condenses in a cooler area, and is collected.
Decantation
- Separates a liquid from a solid by carefully pouring off the liquid.
- Relies on density differences.
