Colligative properties Flashcards
1
Q
colligative properties…
A
properties that depend on the # of particles (concentration), not the identity
2
Q
osmotic pressure (3)
A
- pressure needed to stop osmosis from starting
- pressure exerted on solution once it completes osmosis
- more particles in solution=greater osmotic pressure
3
Q
diffusion
A
the net movement of particles from a region of one concentration to a region of a different concentration
4
Q
osmosis
A
diffusion of solvent from low to high concentration across a semipermeable membrane (solute cannot cross!)
5
Q
Isotonic
A
solution with same osmotic pressure as body fluids
6
Q
hypotonic
A
solution with lower osmotic pressure than body fluids
7
Q
hypertonic
A
solution with higher osmotic pressure than body fluids
8
Q
being in a hypertonic solution causes ____
A
crenation (shriveling)
9
Q
being in a hypotonic solution causes……
A
hemolysis (swelling)
