Mixtures are made up of two or more different kinds of Pure Substances.
Homogenous Mixtures — Mixtures wherein only one phase is discernible with uniform composition and properties throughout. Commonly called solutions and can be separated into their component substances by physical methods, such as Distillation and crystallization.
- Concentration — Measure of the relative amounts of the components of a solution
- Solute — The component that dissolves the solution.
- Solvent — The component that dissolves other components of the solution. Typically water.
- Solubility — The maximum amount of Solute that can be dissolved in a particular Solvent under specific conditions; often a ratio. Greatly depends on the Intermolecular Forces of the solute and solvent.
- Saturation — When a solid solute or particle is mixed with a liquid solvent, the solid solute may dissolve (Dissolution) or precipitate (crystallization)
- Saturation Point — The point where no more solute can be dissolved in the solvent at a particular temperature.
- Types of Saturation — Unsaturated, Saturated, Supersaturated
Heterogenous Mixtures — Mixtures wherein two or more distinct phases are discernible; not uniform in composition and properties throughout.
- Suspensions — Particles are too large or too heavy to be carried by the particles they are suspended in, causing them to settle after some time.
- Colloids — Suspended particles are small and light enough to be carried by the movement of the particles in which they are suspended in.
