Solutions

Types of Heterogenous Mixtures
- ^^Suspension^^: a heterogenous mixture of a fluid and large particles that will settle out over time
- ^^Colloid^^: a heterogenous mixture in which the dispersed particles will not settle out
^^Solvation^^: the process of dissolving a solute into a liquid
- ^^Dissociation^^: the physical separation of the ions in a solid ionic compound by the action of a solvent
^^solubility^^: The maximum amount of solute into a liquid solvent
Separating Mixtures
- Evaporation
- Magnetism
- Filtering/Sifting
- Distillation

Saturation
- ^^Concentration^^: the actual amount of solute dissolved in a given amount of solution
- ^^Saturated Solution^^: a solution that contains the maximum amount of solute that it can hold at a given temperature
- ^^Unsaturated Solution^^: a solution that contains less than the maximum amount of solute that it could hold at a given temperature
- ^^Supersaturated Solution^^: a solution that contains more than the maximum amount of solute that it can normally hold at a given temperature

^^Colligative Property^^: a physical property of solutions that depends only on the concentration of dissolved particles and not on the identity or properties of the solute
- %%Boiling Point Elevation%%: the increase in the boiling point of a solvent due to the presence of dissolved solute
- %%Freezing Point Depression%%: the lowering of the freezing point of a solvent due to the presence of a dissolved solute
