Osmosis Flashcards
1
Q
What are osmotica?
A
Solutes that are osmotically active.
2
Q
What is osmosis?
A
The diffusion of water through a selectively permeable membrane.
3
Q
Examples of osmotica?
A
IONS
Sugars
Proteins
4
Q
Osm/L=
A
Molar concentration X number of molecules or ions in solution
5
Q
1st step in Osmolarity?
A
Does the solute cross the cell membrane via simple passive diffusion?
6
Q
2nd step in Osmolarity?
A
When the solute dissolves, does it remain intact or dissociate into ions?
7
Q
What inherit energy do molecules contain that makes them move around randomly?
A
Thermal energy
8
Q
When does diffusion end?
A
When the concentration is the same on both sides of the synthetic membrane?
