5 Matching questions

  1. Electrolyte solution
  2. saturated solution
  3. Mass percent
  4. Vapor Pressure Lowering
  5. What are the four colligative properties
  1. a contains max amount of solute that can dissolve in solvent
  2. b conducts electricity (ions present)(salt)
  3. c - when a solute is adapted to a solvent, then the vapor pressure is lowered
  4. d mass solute over mass solution
  5. e - vapor pressure lowering
    - boiling point elevation
    - freezing point depression
    - osmotic pressure

5 Multiple choice questions

  1. attraction between the same molecules (H2O and H2O)
  2. will partially ionize in H2O
  3. solutions form when the solvent-solute interactions are stronger than the solute-solute and solvent-solvent interactions
  4. 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. ...

5 True/False questions

  1. Concentrationquantified amount of solute in a solvent

          

  2. Why are hydrogen bonds so important?DNA is held together by H-bonds
    The reason why what has its unique properties

          

  3. Lattice energy is endothermic- when a solute is adapted to a solvent, then the vapor pressure is lowered

          

  4. solubility is effected bytemperature
    - solubility of a solid in a liquid increases with a temp increase
    - solubility of a gas in liquid decreases with a temp increase
    pressure
    - solubility of a solid in liquid is not effected by pressure
    - solubility of a gas in liquid increases with an increase in pressure

          

  5. Melting/Fusionsolid to liquid add PE
