Test 3 -- Ch 7-9
Force acting on specific area
0 c or 273 K
1 atm or 760 mmHg
1 mol = 22.4 L
760 torr or mmHg
Substance present in greater amt. (water)
Substance present in small amt.
Ionic and Polar Solutes
strong solute-solute between (+) (-) ions.
under go Hydration
Like disolves like, non-polar won't interact with polar
Produce ions and conduct electricity.
Dissociate in water to produce (+)(-) ions.
Forms solution of a few ions and mostly undissociated molecules
solubility ^ as pressure ^ on a gas.
amt solute/amt solution
Mass of solute(g)/ Total mass (solvent+solute)(100)
Volume of solute/ Volume of solution (100)
Grams of solute/mm of solution (100)
moles of solute in sol'n.
Mol solute/L of sol'n.
Medium sized particles that don't settle in water and can be separated by a semipermeable membrane.
Large particles that settle out and have to be mixed to stay suspended can be separated by a filter.
H2O flows from a lower solute concentration into a higher solute concentration.
produced by solute particles, pressure that prevents the flow of additional h2o into more concentrated areas.
same osmotic pressure on RBC's.
5% glucose, .9% NaCl
^ in osmotic pressure on RBC's, h2o flows out of RBC's causing crenation
decrease in osmotic pressure on RBC's, h2o flows into RBC's hemolysis.
