5 Matching questions

  1. What are the four colligative properties
  2. Osmotic pressure
  3. Deposition
  4. Freeze
  5. Concentration
  1. a gas to solid remove PE
  2. b osmosis: solvent will flow through a semi-permeable membrane that separates a solution from a pure solvent
    - the solution will be diluted
    - the solvent will flow from low to high concentration
    the pressure that is applies to high concentration side to stop the flow of solvent is osmotic pressure
  3. c quantified amount of solute in a solvent
  4. d - vapor pressure lowering
    - boiling point elevation
    - freezing point depression
    - osmotic pressure
  5. e liquid to solid remove PE

5 Multiple choice questions

  1. gas to liquid remove PE
  2. will ionize completely in H2O
  3. properties that depend only on the amount of the solute present, not on the type of solute.
  4. an extreme case of dipole-dipole interactions. Only occurs when hydrogen in directly bonded to N, O, F.
  5. moles of solute over liters of solution

5 True/False questions

  1. intermolecular forcesforces between atoms within a molecule


  2. solventsubstance present in the largest amount


  3. unsaturated solutionconducts electricity (ions present)(salt)


  4. Why do solutions form?solutions form when the solvent-solute interactions are stronger than the solute-solute and solvent-solvent interactions


  5. Surface tensionamount of energy required to stretch or increase the surface of liquid by a unit of area; strength of this "skin" is directly proportional to the IMF
