1. Solution Chemistry

2. Solutions Homogeneous mixtures of substances composed of at least one solute and one solvent

3. Solute A substance that is dissolved, such as salt

4. Solvent The medium in which a solute is dissolved, such as water

5. Electrolytes Aqueous solutions that conduct electricity

6. Nonelectrolytes Aqueous solutions that do not conduct electricity

7. Dissociation The separation of ions that occurs when an ionic compound dissolves in water

8. Ionization the process by which a neutral atom or molecule is converted to an ion

9. Pure Substance Consists of only 1 particular kind of matter and therefore always has the same composition and properties throughout

10. Pure substances are classified into ELEMENTS (i.e. Fe, O2) or COMPOUNDS (i.e. H2O, CO2)

11. Mixture A combination of 2 or more pure substances, each of which retains its own chemical and physical properties

12. Heterogeneous mixture a non-uniform mixture consisting of more than 1 phase (portion)

13. Homogeneous Mixture A solution uniform throughout, cannot see the different parts of the mixture

14. Liquid Solutions Made by dissolving solids, liquids or gases in liquids i.e. sugar in water, methanol in water, carbon dioxide in water

15. Gaseous Solution Made by dissolving solids, liquids or gases into gas. All gases mix in all proportions to produce solutions

16. Solid Solution Made by mixing solids, liquids or gases with a solid substance i.e. alloy metals (brass is zinc dissolved in copper)
