  5. Mass percent
  1. a contains max amount of solute that can dissolve in solvent
  2. b light will scatter on a colloid because of the larger particles
  3. c moles of solute over liters of solution
  4. d 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
  5. e mass solute over mass solution

5 Multiple choice questions

  1. - the freezing point of a solution is lower than the freezing point of the pure solvent
  2. solution concentration is greater than cell fluid concentration
    - H2O out of cell to solution and cell crunches
  3. liquid to solid remove PE
  4. an extreme case of dipole-dipole interactions. Only occurs when hydrogen in directly bonded to N, O, F.
  5. ...

5 True/False questions

  1. Viscositystuff present in the lesser amount


  2. Vapor Pressure Lowering- when a solute is adapted to a solvent, then the vapor pressure is lowered


  3. Sublimationsolid to gas add PE


  4. What does the phase of a pure substance depend on?IMF, temperature, pressure


  5. Dispersion of London Forcesexists between all molecules and ions; a temporary induced dipole.
