Lesson Frame Essential Question: What does it mean to have solutions with different saturation levels? I will… know what solutes, solvents, solutions are. understand the concept of saturation. By the end of this lesson I will be able to… Explain how to create a saturated and supersaturated solutions.

Solubility

Foldable Set-up

Solubility Solubility - how easily a substance (solute) dissolves in another substance (solvent) to form a solution

Solutions Solute Ex) Glass of Kool-Aid Solvent Solute Solution the substance that does the dissolving Usually present in a greater amount Ex) water a mixture in which the solute is evenly mixed throughout the solvent Ex) Glass of Kool-Aid the substance that is being dissolved Present in a lesser amount Ex) powdered Kool-Aid mix If a substance dissolves in the solvent  SOLUABLE If a substance doesn’t dissolve in the solvent  INSOLUABLE

Concentrated Solution Concentration Dilute Solution Concentrated Solution has only a little solute dissolved in a certain amount of solvent. has a lot of solute dissolved in a certain amount of solvent.

Unsaturated solutions Supersaturated solutions Saturation Unsaturated solutions Saturated solutions Supersaturated solutions solutions that can still dissolve more solute in it. solutions that have more solute than you would normally expect to dissolve solutions that have the maximum amount of solute and no more will dissolve.

Supersaturated Borax Solution

Exit Ticket Explain how you would create a saturated solution of sugar water. Explain how you would create a supersaturated solution of sugar water. What will eventually happen to the supersaturated solution?
