  1. What is a Solute?

  2. What is a Solvent?

  3. Solubility of a Substance

  4. Solubility Curve • The relationship between the ___________in water and ___________. • Temperature is the ____________ variable (x-axis).

  5. 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.

  6. 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).

  7. 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.

  8. 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.
