  1. What is a Saturated Solution?
    A solution containing the maximum amount of solute that can be dissolved at a given temperature.
  2. What are colligative properties?
    They depend upon the number of particles of solute in the solution, not the identity of the solute.
  3. What does miscible mean?
    Describes liquid that dissolve in eachother.
  4. What is molarity?
    The number of moles of solute dissolved in 1 L of solution.
  5. What is an unsaturated solution?
    It contains less solute than can theoroletically be dissolved.
  6. What is a concentrated solution?
    A solution with a large amount of solute compared to the solvent.
  7. What is Henry's Law?
    At a given temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid.
  8. What is a dilute solution?
    A solution that contains only a small amount of the maximum of the maximum amount of solute that can be dissolved at a given temp.
  9. Increasing the temp. of a liquid-solid solution will...
    Increase the rate at which a crystalline solute dissolves, and increase the amount of crystaline solute that dissolves.
  10. To make a substance dissolve faster in a solvent you can...
    • agitation (shaking/stirring)
    • raise the temp.
    • crush the substance to a poweder
  11. As pressure of a gas above a liquid decreases, the Solubility of the gas in the liquid...
    Decreases.
  12. What are the colligative properties of a solution?
    • Boiling Point Elevation
    • Vapor Pressure Lowering
    • Freezing Point Depression
  13. If more solvent is added to a solution...
    The molarity decreases
