  1. Solutions and Solubility April 1, 2004 BY: BRIANNA SHIELDS

  2. DO NOW • 1. A mixture that is homogeneous throughout but cloudy is most likely what type of mixture? • 2. A substance that is made when several elements are chemically combined is known as? • 3. What type of substance is on the front counter?

  3. Please get your homework out! • We are going to correct the homework now • You are responsible for following along and correcting any incorrect answers

  4. GOAL • To state the parts of a solution and know the meaning of soluble and insoluble.

  5. Work with your partner- Without using your notes, list all the characteristics of a solution • Homogeneous mixture • Won’t settle • Same throughout • Light passes through/ no scattering • Transparent (usually) • One substance dissolved in another

  6. What are some examples of solutions? • Colored water • Kool-aid • Pulpless lemonade • Ocean water • Air

  7. Solute Solvent Substance that is dissolved Substance that is doing the dissolving Solutions

  8. What would the solutes and solvents be? • Lemonade? • Solutes: lemon, sugar • Solvent: water • Ocean water? • Solute: salt • Solvent: water

  9. Soluble Insoluble Substance that dissolves/breaks apart in another substance Sugar is soluble in water A substance that will not dissolve in another Oil is insoluble in water Solubility

  10. Label these as soluble or insoluble in water • Alcohol in water? • Soluble • Iron in water? • Insoluble • Lighter fluid in water? • Insoluble • Salt in water? • Soluble

  11. Solubility 1. The amount of solute that can dissolve in a solvent at a certain temperature 2. “How well can a substance dissolve in another” Solubility

  12. Solubility is affected by: 1. Temperature 2. Stirring 3. Grinding 4. Solute concentration Solubility

  13. Solubility Curves • Look at your copy: • Solubility curves are used to determine how well solutes will dissolve in a solvent at certain temperatures

  14. How much salt will dissolve per 100 g of water at 60 degrees Celsius?

  15. 1. Which of these substances is the most soluble in water? 2. What seems to happen to solubility as temperature increases? 3. Are there any solutes that act in the opposite manner?

  16. 1. Which is the most soluble solute?? 2. At what temperature do NaNO3 and KNO3 have equal solubilities? 3. How about NaCl and KClO3?
