  1. Solubility What is solubility? How do I interpret solubility curves? Conditions of Solution Equilibrium

  2. You order SWEET tea on a hot day. • It arrives and you take a giant gulp. • YUCHKG! They served you unsweet and the waiter is nowhere in sight. • Sugar packets are on the table. • Do you dare? Why or why not?

  3. Will these substances mix? • Can you explain why or why not? • Water and Vinegar • Lithium chloride and water • Water and oil • Gasoline and alcohol

  4. What is Solubility? • Solubilitydepends on: • Nature of the solute and solvent • Temperature • Pressure (for gases)

  5. Solubility is … • Solubility = the amount of substance required to form a saturated solution with a specific amount of solvent at a specified temperature. • grams of solute per 100 grams of solvent • TEMPERATURE must be specified • Pressuremust be specified. • GENERALLY – Solubility increases as Temp increases. • But NOT ALWAYS TRUE! Exceptions: NH3, SO2, HCl

  6. Solubility Curves

  7. Practice with Solubility Curves

  8. Three conditions of solution equilibrium: • Unsaturated Solution: contains less solute than a saturated solution • Saturated Solution: contains maximum amount of dissolved solute at specified temp • Supersaturated Solution: contains more dissolved solute than a saturated solution

  9. Examples • Carbonated water is supersaturated with carbon dioxide • Air can be supersaturated with water forming clouds/precipitation • Hand Warmers use supersaturated sodium acetate.
