Study Notes
Definitions of Mixtures
- Colloid: A homogeneous mixture featuring medium-sized particles that are visible but do not settle or can be filtered out.
- Suspension: A heterogeneous mixture containing large particles that are visible and capable of settling or being filtered.
- Solution: A homogeneous mixture consisting of tiny particles that are imperceptible, cannot settle, and cannot be filtered out.
Classification of Mixtures
- Heterogeneous mixtures: Characterized by different components that are dissimilar, allowing for visible separation.
- Homogeneous mixtures: Composed of components that are alike and uniform throughout, with no visible separation.
Components of Solutions
- Solvent: The substance in a solution that facilitates dissolving the other component; it does not undergo dissolution itself.
- Solute: The substance in a solution that is dissolved by the solvent.
Separation Techniques
- Various methods to separate components of mixtures include filtering, boiling, distillation, and chromatography, utilizing physical processes to achieve separation.
