Solutions and Dilutions Flashcards
Diffusion
Movement of molecules from HIGH to LOW concentration
Osmosis
Movement of water from LOW to HIGH concentration
Henry’s Law
Dissolved gas in a liquid is proportional to partial pressure of the gas
Hypotonic Solution
Lower osmolarity than the cytoplasm
Hypertonic Solution
Greater osmolarity than the cytoplasm
Isotonic Solution
Same osmolarity as the cytoplasm
Osmolarity
Total molar concentration of all solutes
Osmotic Pressure
Pressure needed to stop the flow of solvent across the membrane
Saturated Solution
Max amount of solute that can be dissolved at a temperature
Supersaturated Solution
More particles than could be dissolved by solvent
Serial Dilution
Regular increments of dilutions that are less concentrated than the last
Solute
Component of solution less than the solvent
Solution
Homogeneous mixture composed of one or more solutes
Solvent
Component of solution that is the largest quantity
Tonicity
The ability to make water move in or out of the cell
