13.1 solutions

  1. 1. Solutions 13.1
  2. 2. Mixtures <ul><li>A solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase. </li></ul><ul><ul><li>Stable…no settling. </li></ul></ul><ul><ul><li>In a homogeneous mixture the particles are molecule-sized, so the mixture appears to be made of only one substance. </li></ul></ul><ul><ul><ul><li>Homo = looks the same </li></ul></ul></ul><ul><ul><li>The particles of a heterogeneous mixture are large enough to see. </li></ul></ul><ul><ul><ul><li>Hetero = looks different </li></ul></ul></ul>
  3. 3. Suspensions <ul><li>A suspension is a mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas. </li></ul><ul><ul><li>In a suspension, the particles may remain mixed with the liquid while the liquid is being stirred, but later they settle to the bottom. </li></ul></ul><ul><ul><li>Not stable. </li></ul></ul>
  4. 4. <ul><li>Particle Model for a Suspension </li></ul>
  5. 5. Solution <ul><li>Any mixture that is homogeneous. </li></ul><ul><ul><li>Air is a gaseous solution. </li></ul></ul><ul><li>A homogeneous liquid mixture: </li></ul><ul><ul><li>one main component—a liquid </li></ul></ul><ul><ul><li>one or more additional ingredients that are present in smaller amounts. </li></ul></ul>
  6. 6. Solutions <ul><li>The solvent is the primary ingredient in a solution. </li></ul><ul><ul><li>Water is the most common solvent. </li></ul></ul><ul><ul><li>Water is known as the universal solvent. </li></ul></ul><ul><li>The other ingredients are the solutes. </li></ul><ul><ul><li>Solutes are dissolved in the solvent. </li></ul></ul><ul><li>Aqueous solutions have water as the solvent. </li></ul>
  7. 7. Solid Solutions? <ul><li>Another type of solution involves one solid mixed with another solid. </li></ul><ul><ul><li>Examples include alloys such as: </li></ul></ul><ul><ul><ul><li>brass, bronze, and steel </li></ul></ul></ul><ul><ul><ul><li>The “gold penny” you made in lab was really brass. </li></ul></ul></ul>
  8. 8. Liquid and Solid Solutions
  9. 9. <ul><li>Gold and Gold Alloy </li></ul>
  10. 10. Colloids <ul><li>A colloid is a mixture. Particles are middle sized . </li></ul><ul><ul><li>Bigger than solution but smaller than </li></ul></ul><ul><ul><li>Stable </li></ul></ul><ul><ul><li>Homogeneous </li></ul></ul><ul><ul><li>Example: Milk </li></ul></ul><ul><ul><ul><li>Looks homogeneous. But milk contains fat and lumps of casein (protein) in a liquid called whey. </li></ul></ul></ul>
  11. 11. Colloids show up in light.
  12. 12. Separating Mixtures <ul><li>Mixtures are separated based on their physical properties. </li></ul><ul><ul><li>Filtering, settling, evaporation… </li></ul></ul><ul><li>Chromatography separates by differences in attraction. </li></ul>
  13. 13. Distillation <ul><li>Separates by differences in boiling point </li></ul><ul><li>As one component reaches its boiling point, it evaporates from the mixture and is allowed to cool and condense. This is called a distillate. </li></ul><ul><ul><li>Salt water can be boiled to make pure water. When the water boils away the salt is left behind. </li></ul></ul>
  14. 14. READ CHAPTER 13 SECTION 1 <ul><li>ADD ANY VOCAB THAT I DID NOT COVER TO YOUR 13.1 NOTES. </li></ul><ul><li>DO: p.459 1-12 </li></ul>
