1. Mixture Two or more materials stirred together or combined

2. Solution A special mixture formed when a material dissolves in another material and the result is clear

3. Dissolving A process in which one material disperses uniformly in another material, so that the first material seems to disappear

4. Property A characteristic of an object; something you can observe such as size, color, shape, or texture

5. Evaporation This causes liquids to dry up. The liquid turns to gas and disperses into the air leaving any dissolved material behind.

6. Solute The part of a solution that dissolves in the Solvent

7. Solvent The part of a solution that something is dissolved into.

8. Volume The 3-dimensional amount of space that a gas, solid or liquid takes up.

9. Saturation A solution reaches saturation when no more solute material can be dissolved into the solvent

10. Soluble The ability of a solute to dissolve in a solvent.

11. Concentration The amount of material dissolved in a measure of solvent

12. Dilute To make a solution less concentrated, usually by adding more solvent. Or the solution of the two that is less concentrated when comparing.

13. Chemical Reaction When two or more materials are mixed together and a change occurs resulting in a new material being formed with different properties from the original materials.

14. Reactants Chemicals that react to one another to cause a chemical change

15. Precipitate A solid material that forms as a product of a reaction that has different properties from the reactants from which it was formed
