Pressure has ____ affect on solubilty of solids and liquids.
little
Henry’s Law equation:
C=kP
C=concentration of dissolved gas
k=constant
P=partial pressure of gas solute above the solution
Amount of gas dissolved in a solution is ______ proportional to the pressure of gas above the solution.
directly
Solubilty of a gas in solvent typically (increases/decreases) with increasing temperature.
decreases
Define volatile:
tendency of a substance to vaporize.
Nonvolatile solute _______ the vapor pressure of a solvent.

Raoult’s Law Equation:
Psoln=XsolvP°solv
Psoln = observed vapor pressure of solution
Xsolv = mol fraction of solvent
P°solv = vapor pressure of pure solvent
