1. (8th) Chapter 7-1 Cornell Notes “Understanding Solutions”

2. (8th) Chapter 7-1 Cornell Notes Key Questions What are the characteristics of solutions, colloids, and suspensions? What happens to the particles of a solute when a solution forms? How do solutes affect the freezing point and boiling point of a solvent?

3. (8th) Chapter 7-1 Cornell Notes Key Terms solution- solvent solute colloid suspension

4. (8th) Chapter 7-1 Cornell Notes Paragraph 1 solution: mixture solvent and one or more solutes; solvent: largest amount in a solution; solute: smallest part in solution, dissolved by solvent; solution homogeneous, solute particles too small to see. 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org

5. (8th) Chapter 7-1 Cornell Notes Paragraph 2 water: “universal solvent; life dependent on water; Examples: tree sap, blood, saliva, tears. 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org

6. (8th) Chapter 7-1 Cornell Notes Paragraph 3 solvents not always water; can be any combination gases/liquids/solids. 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org

7. (8th) Chapter 7-1 Cornell Notes Paragraph 4 Mixtures also include colloids and suspensions; colloid: mixture containing small, undissolved particles; particles larger than in a solution; too small to see easily but still scatters light beams; same properties throughout; Examples: fog, gelatin, mayonnaise, shaving cream. 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org

8. (8th) Chapter 7-1 Cornell Notes Paragraph 5 suspension: particles easily seen, easy to separate out w/ filtration or settling; does not have same properties throughout; some particles different sizes. 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org

9. (8th) Chapter 7-1 Cornell Notes Paragraph 6 solution: solvent particles surround/separate solute particles, ionic solid + water: (-) and (+) ions separated by water molecules (conducts electricity); molecular solid + water: breaks down into neutral molecules (does not conduct electricity). 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org

10. (8th) Chapter 7-1 Cornell Notes Paragraph 7 : solutes lowers freezing point of solvents (harder for solvent to form crystals; raises boiling point of solvents (more E needed to escape as a gas. 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org
