there are two or more solutes on one side of a semipermeable membrane. if a concentration gradient is present for a solute that can pass through this particular membrane it will diffuse and be separated from the other solutes.
movement of water through a semipermeable membrane from an area of higher concentration of water to an area of lower concentration of water
rupturing of the cell membrane of an erythrocyte resulting in loss of hemoglobin from the cell
shrinking or shriveling of a cell due to loss of water from the cytoplasm
the amount of a substance equal to its molecular weight.
- a mole f any substance always contains
- 6.02 X 1023 molecules (Avogadro's number)
a mole of molecules mixed in enough water to make one liter of solution
the pressure that must be placed on a solution to keep pure water from entering it across a semipermeable membrane. (it is really a measure of the concentration of solute in a solution)
unit for measuring osmotic pressure
1osmol = pressure of a mole of NON-IONIZING solute molecules in a liter of solution
