  1. soluble
    capable of being dissolved
  2. solution
    homogeneous mixture of 2 or more substances in a single place
  3. solvent
    dissolving medium in a solution
  4. solute
    substance dissolved in a solution
  5. suspension
    particles in a solvent are so large they settle out unless the mix is constantly stirred or agitated
  6. colloids
    particles that are intermediate in size between those in solutions and suspensions form this mix
  7. Tyndall effect
    occurs when light is scattered by colloid particles dispersed in a transparent medium
  8. electrolyte
    a substance that dissolves in water and conducts electricity
  9. nonelectrolyte
    a substance that dissolves in water and DOES NOT conduct electrical currents
  10. solution equilibrium
    the physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates
  11. saturated solution
    a solution that contains the max amount of dissolved solute
  12. unsaturated solution
    a solution that contains less solute than a saturated solution under the existing conditions
  13. supersaturated solution
    a solution that contains more dissolved solute than a saturated slution contains under the same conditions
  14. solubility
    the amount of a substance required to form a saturated solution with a specific amount of solvent at a specific temp
  15. hydration
    a solution process with water as the solvent
  16. immiscible
    liquids that are not soluble in each other
  17. miscible
    liquids that dissolve freely in one another in any proportion
  18. Henry's law
    the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid
  19. effervescence
    the rapid escape of a gas from a liquid in which it is dissolved
  20. solvated
    a solute particle that is surrounded by solvent molecules
