  1. a measure of the amount of solute that is dissolved in a specified amount of solution
    concentration
  2. a process by which water (solvent) is added to a solution to increase the volume and decrease (dilute) the solute concentration
    dilution
  3. the separation of a solute into ions when the solute is dissolved in water
    dissociation
  4. a substance that produces ions when dissolved in water; its solution conducts electricity
    electrolyte
  5. the solubility of a gas in a liquid is directly related to the pressure of that gas above the liquid
    henry's  law
  6. the process of surrounding dissolved ions by water molcules
    hydration
  7. an ionic compound that does not dissolve in water
    insoluble salt
  8. an equation for a reaction in solution that gives all the individual ions, both reacting ions and spectator ions
    ionic equation
  9. the grams of solute in exactly 100 grams of solution
    mass percent
  10. the number of moles of solute in exactly 1L of solution
    molarity (M)
  11. an equation for reaction that gives only the reactants undergoing chemical change and leaves out spectator ions
    net ionic equation
  12. a substance that dissolves in water as molecules; its solution will not conduct an electrical current
    nonelectrolyte
  13. a solution containing the maximum amount of solute that can dissolve at a given temperature. any additional solute will remain undissolved in the container
    saturated solution
  14. the maximum amount of solute that can dissolve in exactly 100g of solvent, usually water, at a given temperature
    solubility
  15. an ionic compound that dissolves in water
    soluble salt
  16. the component in a solution that changes state upon dissolving; if no change in state occurs, it is the component present in the smaller quantity
    solute
  17. a homogeneous mixture in which the solute is made up of small particles (ions or molecules)
    solution
  18. a compound that ionizes completely when it dissolves in water. its solution is a good conductor of electricity
    strong electrolyte
  19. a solution that contains less solute than can be dissolved
    unsaturated solution
  20. a percent concentration that relates the volume of the solute to the volume of the solution
    volume percent
  21. a substance that produces only a few ions along with many molecules when it dissolves in water. its solution is a wake conductor of electricity
    weak electrolyte
  22. the substance in which the solute dissolves; usually the component present in greatest amount
    solvent
  23. the substance present in the smallest amount in a mixture
    solute
  24. the solute is dispersed in to the
    solvent
  25. the particles of the solute are evenly dispersed among the molecules of the solvent
    solution
  26. for solids or liquids to form solutions there must be an attraction between
    solute particles and solvent particles
  27. forms solutions easlily
    gas
  28. solutes can be classified by their ability to
    conduct an electrical current
  29. when electrolytes dissolve in water they separate into
    ions
  30. ions can conduct
    electricity
  31. affect a solute solubility
    • type of solute
    • type of solvent
    • temperature
  32. unit for soulubility
    grams
  33. the solubility of a gas in water decreases as the
    temperature increaes
  34. forms when two solutions of ionic compounds are mixed
    precipitate
  35. concentration of a solution= amount of solute/amount of solution
    formula for concentration of a solution
  36. how to increase the solubility of a gas
    • 1. lower temp
    • 2. increase the pressure of the gas
