Question:
tyndall effect.

Answer:
the scattering of light by colloid particles



Question:
brownian motion.

Answer:
motion of any colloidal particle suspended in a solvent EX. Dust



Question:
dispersing medium.

Answer:
material that particles are dispersed Examples: smoke, clouds, marshmellows, whipped cream



Question:
osmosis.

Answer:
passage of a solvent through a semipermeable membrane separating a dilute solution from a more
concentrate solution



Question:

,semipermeable membrane.

Answer:
membrane that allows certain types of molecules to pass through it but prohibits the passage of other
types of molecules



Question:
osmotic pressure.

Answer:
pressure that must be applied to prevent the net flow of solvent through a semipermeable membrane
from a solution of lower solute concentration to a solution of higher solute concentration



Question:
osmolarity.

Answer:
product of a solution molarity and the number of particles produced per unit if the solute is
dissociated i x M i = number of particles of solute



Question:
isotonic solution.

Answer:
solution surrounding cells has the same osmotic pressure as the cells saline.9% m/v



Question:
hypotonic solution.

Answer:
lower osmotic pressure than within cells, water flows into cells Ex. distilled water

,Question:
hemolysis.

Answer:
causes cell to swell and eventually rupture



Question:
hypertonic solution.

Answer:
solution with higher osmotic pressure than within the cells. Water flows out and shrinks.



Question:
crenation.

Answer:
shrinking of cells due to loss of water



Question:
dialysis.

Answer:
process where a semipermeable membrane allows passage of a solvent dissolved ions and small
molecules, but blocks colloidal size particles and large molecules Ex. proteins



Question:
hemodialysis.

Answer:
kidneys fail, artificial kidney uses hemodialysis to remove waste particles, such as urea, from blood
