Study Notes

Homogenous Mixtures

Composed of two or more substances uniformly distributed throughout.
Example: Saltwater where salt dissolves evenly in water.

Heterogeneous Mixtures

Contain different substances that remain distinct from one another.
Always exhibit more than one phase, meaning different parts can be identified easily.
Can exist as suspensions or colloids, depending on the particle size and behavior in a medium.

Suspensions

A type of heterogeneous mixture with solid particles that may remain momentarily suspended in a liquid.
Requires mechanical agitation (e.g., shaking) to maintain particle dispersion.

Colloids

Mixtures appearing homogeneous but are technically heterogeneous due to the size of their particles.
Exhibit properties of both solutions and suspensions yet remain visually uniform.

Solutions

Defined as homogeneous mixtures with two or more components that are evenly distributed.
Consist of a solute (the substance being dissolved) and a solvent (the substance doing the dissolving).
Can be categorized into three types: gaseous, liquid, and solid solutions, based on their state.
