Properties of solutions

  1. Relationship between lattice energy and solubility
    As lattice energy increases solubility decreases
  2. Effect of temperature on the solubility of gasses and ionic solids
    As temperature increases the solubility of gasses decreases while the solubility of ionic solids increases
  3. Henry's Law
    As the partial pressure of a gas over a solution increases the solubility of that gas increases

    S=KhP
  4. Molarity
    Molarity (M)

    M=moles of solute/L of solution
  5. Molality
    Molality (m)

    m=moles of solute/Kg of solvent
  6. Mass Percent
    Mass % = mass of solute/mass of solution
  7. Mole Fraction (X)
    XA = Moles of A/Total moles of solution
  8. Raoult's Law
    The vapor pressure of A is the product of the mole fraction of A times the vapor pressure of pure A

    PA = PA0XA
  9. Vapor pressure in a solution with a non-volatile electrolyte
    The vapor pressure is the product of the pure solvent times the mole fraction of the non-volatile solute

    PA = PA0XB
  10. Vapor pressure when solute and solvent have similar intramolecular forces, that is they are miscible
    Ptot = PA0XA + PB0XB
