Colligative properties

Question 1

Formation of ion pairs ____ the actual value compared to the theoretical

Answer 1

decreases

Question 2

molarity

Answer 2

mol solute/ L solution

Question 3

molality

Answer 3

mol solute/ kg solvent

Question 4

dissolved solute (outside) = dissolved solute (inside)

Answer 4

no net flow (equilibrium)

Question 5

dissolved solute (outside) > dissolved solute (inside)

Answer 5

flow out (cell shrinks)

Question 6

dissolved solute (outside) < dissolved solute (inside)

Answer 6

flow in (cell swells)

Question 7

isotonic solution

Answer 7

total solute concentration in the solution matches that inside the cell

Question 8

hypertonic solution

Answer 8

Total solute concentration in the solution is greater than that inside the cell; water leaves the cell, cells shrink

Question 9

hypotonic solution

Answer 9

total solute concentration in the solution is less than that inside the cell; water enters cells; cells expand

Question 10

reverse osmosis

Answer 10

Process in which solvent is forced through a semipermeable membrane, leaving a more concentrated solution behind
