Presentation Transcript
solubility curve
Solubility Curve
  • The relationship between the ___________in water and ___________.
  • Temperature is the ____________

variable (x-axis).

saturated solution
Saturated Solution
  • The ____________ amount of solute a solvent can dissolve at a given _________.
  • Any data point that falls ____ the curve of the graph is a saturated sol’n.
unsaturated solution
Unsaturated Solution
  • If you can add more solute to a solution and it will still dissolve, then the solution is classified as __________
  • On a solubility graph, it will fall ______ the curve for the specific solute (NaCl).
supersaturated solution
Supersaturated Solution
  • A solution that contains __________than it can normally dissolve per a given amount of water.
  • This happens by cooling a saturated sol’n to make it supersaturated.
  • Any data point that is _______ the solubility curve is classified as a supersaturated sol’n.
seed crystal
Seed Crystal
  • A crystal of the solute added to a ___________________so the excess solute will precipitate out (crystals form).
  • Example - ____________- seed crystal is added to crystallize a supersaturated solution of sugar water.
