Presentation Transcript

  1. Solubility

  2. Solubility • When a substance dissolves in another substance, it is said to be soluble • Examples: • Salt or sugar in water • Laundry detergent in water • Nail polish in nail polish remover

  3. Solubility • When a substance will not dissolve in another substance, it is said to be insoluble • Examples: • Oil in water • Sharpie marker in water • Vinegar in oil

  4. Factors Affecting Solubility • Most of the time, as the temperature of a solvent increases, the solubility of a solute increases • For a few substances, the temperature does not have much effect on solubility or as the temperature of the solvent increases, the solubility of the solute decreases.

  5. Solubility • Solubility is the amount of a solute that will dissolve in a given amount of solvent • Solubility is generally given as the maximum number if grams of the substance that will dissolve in 100g of a solvent at a certain temperature. • The amount of solute that will dissolve in a given amount of solvent depends on a number of factors, including temperature.

  6. Solubility • Most of the time, as the temperature of a solvent increases, the solubility of a solute increases • For a few substances, the temperature does not have much effect on solubility or as the temperature of the solvent increases, the solubility of the solute decreases.

  7. Limits of Solubility • Saturated Solution – a solution that has dissolved all of the solute it can normally hold at a given temperature • Unsaturated Solution – a solution that can dissolve more solute at a given temperature • Supersaturated Solution – a solution that contains more solute than a saturated solution at that temperature.

  8. How Can You Tell? • Saturated Solution – if you add a tiny bit more solute to the solution and it does not dissolve, it is a saturated solution. • Unsaturated Solution – if you add a tiny bit more solute to the solution and it does dissolve, it is an unsaturated solution. • Supersaturated Solution – if you add a tiny bit more solute to the solution and the solute comes out of solution, it is a supersaturated solution.
