Flashcards
- Mixture
- A combination of two or more substances that keep their own properties and can be separated physically.
- Heterogeneous mixture
- A mixture with unevenly distributed components that you can see separately; like salad or trail mix.
- Homogeneous mixture
- A mixture that looks the same throughout; also called a solution; like salt water or air.
- Solution
- A homogeneous mixture where a solute dissolves evenly into a solvent.
- Solute

- Solvent
- The substance that dissolves the solute; water is the most common solvent.
- Universal solvent
- A nickname for water because it dissolves more substances than any other common liquid.
- Dissolve
- When a solute breaks into particles too small to see and spreads evenly throughout the solvent.
- Filtration
- Separation method using a filter to remove insoluble solids from a liquid.
- Evaporation
- Separation method where a liquid is heated away, leaving dissolved solids behind.
- Distillation
- Separation technique that uses differences in boiling points to separate liquids from solutions.
- Concentration
- The amount of solute dissolved in a given amount of solvent; a solution can be dilute or concentrated.
- Saturated solution
- A solution that has dissolved as much solute as it possibly can at a given temperature.
- Insoluble
- Unable to dissolve in a particular solvent; sand is insoluble in water.
- Soluble
- Able to dissolve in a particular solvent; salt and sugar are soluble in water.
