Henry Law equation for Cg and Sg Finding |
=Kh*Pg Kh is henrys law constant for gas in solvent Pg is partial pressure of gas above the liquid (mmHg) |
|
|
Raoults Law (Psolution) Finding vapor pressure of solution |
Psolution=XsolventPsolvent X= Mol of solvent / Mol of Solution Psolvent= Vapor pressure of pure solvent |
|
|
A 5% solution |
5 g / 100g sol |
|
|
Hypertonic |
Solute concentration is higher outside cell Water will flow out the cell (cell will shrink) |
|
|
hypotonic |
Solute concentration is lower outside cell water will flow into cell (cell will Grow) can burst |
|
|
isotonic |
Equal!!!! and ideal |
|
|
Reverse Osmosis |
Made by applying extra pressure to cause water to go opposite ways Pressure increases concentration |
|
|
Freezing point depression |
Adding solute causes Freezing point to decrease because disruption between stabilizing intermolecules Lowering VP causes FP to decrease because bonds between molecules keep molecules from staying |
|
|
Boiling point elevation |
Adding Solute causes BP to increase Lowering VP causes boiling point to rise because bonds between molecules keep molecules from escaping |
|
|
tyndall effect |
light scatter can be seen through colloidal solutions |
|
|
colloidal mixtures |
have slight static charge from interaction move via brownian motion (random movement of colloidial particles) |
