osmosis Flashcards
1
Q
what is osmosis?
A
diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane

A
one with very small holes in it
3
Q
do the water molecules pass both ways through the membrane, if so, why?
A
yes, because water molecules move about randomly all the time
4
Q
if more water molecules on one side than the other, what happens?
A
steady net flow of water into region with fewer water molecules
5
Q
what is the formula for change in mass (%)
A
(mass at end - mass at start) / mass at start x 100
