  1. Solubility of Solid in Liquid

    Factors to consider:
    • Type of solid?
    • Type of solvent?
    • Temperature
    • Particle Size
    • Mixing
  2. Solubility of Gas in Liquid

    Factors to consider:
    • Pressure
    • Temperature
    • *higher temp means LOWER solubility
  3. Henry's Law
    C= KP

    • C= solubility
    • K = constant
    • P = atm
  4. Colligative Properties in electrolyte solutions
    Van't Hoff factor (i)

    When solute particles in solutions disassociate
  5. Vapor Oressure lowering (Raoules Law)


    • P1 = solvent
    • P1^0 = pure solvent vapor pressure
    • X1 = mole fraction
  6. Boiling Point Elevation
    • solutions boil at higher temp than the pure solvent

    b is molal boiling pt elevation constant
  7. Freezing Point Depression
    Solutions freeze at lower temp than the pure solvent



    f is molal boiling pt elevation constant
  8. Osmotic Pressure
  9. Osmosis
    selective passage of solvent molecules through a porous membrane from a more dilute solution to a more concentrated one.
  10. reverse osmosis
    • add pressure to get water from more concentrated to less concentrated
    • (salt water to fresh water)
