CONCENTRATIONS & SOLUTIONS Flashcards
c = kP
P is the
pressure of the gas over the solution
Each ion is surrounded by solvent molecules. If the solvent is water, the ions are []
hydrated
Low [] = Low []
Low P = Low C
What are the Intermolecular forces?
Dispersion Forces, H-Bonding, Dipole dipole
contains less solute than the solvent has the capacity to dissolve at a specific temperature.
unsaturated
c = kP
c is the
concentration (M) of the dissolved gas
c = kP
k is a
constant (mol/L*atm) that depends only on temperature
Two substances with similar [] are likely to be soluble in each other.
intermolecular forces
is electrostatically attracted to an O, N, or F atom in another molecule
h-bonding
Factors affecting Solubility
Nature of Solvent, Temperature, pressure
Enthalpy (∆H) changes with each interaction [].
broken or formed
contains the maximum amount of a solute that will dissolve in a given solvent at a specific temperature.
saturated
C2H5OH in H2O
polar molecules are soluble with polar solvents
The solubility of a gas in a liquid is proportional to the pressure of
the gas over the solution
Henry’s law
Nonpolar substances tend to dissolve in []
non polar solvent
are attractive forces between permanent dipoles of two polar molecules
Dipole dipole
