Practice Solutions II Quiz

Know definitions:

á colligative properties

á molarity

á dilution

Be able to explain

á how you dilute a concentrated solution

á how an unsaturated and saturated solution differ

á how you make supersaturated solution (heat a saturated solution)

Know how adding a solute will affect;

á Concentration? Increase or Decrease or Stay the same

á Boiling Point? Increase or Decrease or Stay the same

á Freezing Point? Increase or Decrease or Stay the same

Be able to draw at a molecular level:

á a saturated vs unsaturated

á diluted vs concentrated (YOU ADD WATER TO A CONCENTRATED SOLUTION; THEREFORE, THE DILUTED SOLUTION SHOULD HAVE A GREATER VOLUME OF SOLVENT, BUT BOTH HAVE SAME NUMBER OF SOLUTE PARTICLES.)

Know how to solve dilutions and molarity problems. See HW problems part B, part D and part E.
