  1. heath of the solution
    ΔHsoln = ΔHsolute + ΔHsolvmt + ΔHHmix
  2. heat of the hydration
    ΔHsoln =ΔHlattice + ΔHhydr
  3. henry's law
    Sgas = kH x Pgas
  4. Increasing the volume of a gas causes a _________ in its pressure (Boyle's law), which ______the solubility of the gas.
    decrease,   decreases
  5. As temperature decreases, the solubility of the solution ___________.
    increases
  6. contains the maximum amount of dissolved solute at a given temperature in the presence of undissolved solute.
    saturated
  7. contains less than the equilibrium concentration of dissolved solute. If more solute is added, it will dissolve.
    unsaturated
  8. A solution that contains more than the equilibrium concentration of dissolved solute is called ________.
    supersaturated
  9. of a solute is the maximum amount that dissolves in a fixed quantity of a given solvent at a given temperature,
    solubility (.S’)
  10. An increase in entropy is the natural tendency in both physical and chemical processes..
    enthopy
  11. The solution is _______ to increase the solute’s solubility. When it is _______ slowly, the solubility goes below what is dissolved, but the solute remains dissolved.
    heated,  cooled
  12. Collision Theory: In order for a reaction to occur:
    • Reactant molecules must collide.
    • The molecules must have enough kinetic energy.
    • Reactants must collide in the proper orientation
