Study Notes

Classification of Mixtures

Mixtures are categorized into three types: solutions, colloids, and suspensions, determined by the size of their largest particles.

Types of Mixtures

Solutions: Uniform mixtures consisting of a solvent and one or more solutes, displaying consistent properties throughout.
Colloids: Characterized by small, undissolved particles that remain suspended and do not settle, capable of scattering light.
Suspensions: Contain larger visible particles that can be separated by settling or filtration, exhibiting varied properties throughout.

Detailed Definitions

Solution: Comprises a solvent (largest component) and one or more solutes that are dissolved within it.
Solvent: The component of a solution present in the greatest quantity, often determining the state of the mixture.
Solute: The substance that is dissolved within a solvent, resulting in a solution.

Examples

Solutions: Common examples include soda water, salt water, and grape juice.
Colloids: Milk, shaving cream, and smoke illustrate colloidal mixtures.
Suspensions: Sand mixed with water serves as an example of a suspension, showcasing visible particles.
