  1. Solutions • A homogeneous mixture of 2 or more substances in a single physical state. • Air (O2, N2, others…) • Brass (Cu & Zn) • Ocean Water (H2O, NaCl, others) [http://www.sci.qut.edu.au/courses/undergraduate/undergrad_splash.jpg]

  3. Solutions • Solutions that mix with one another are soluble. • Solutions that are incapable of mixing are insoluble or immiscible. • “Like dissolves like” Click here for a polarity demo. [http://www.chemistry.org/portal/a/c/s/1/resources/ACS/ACSContent/wondernet/images/wn_float_oil.jpg]

  4. Parts of a Solution • Usually when describing liquid & solid: • Solute is the substance being dissolved. • Solvent is the substance “doing” the dissolving. [http://upload.wikimedia.org/wikipedia/commons/8/89/SaltInWaterSolutionLiquid.jpg]

  5. Ionic Substances Dissolved in H2O [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter11/Text_Images/FG11_01.JPG] Click here for video clip of dissolving solids.

  6. Types of Solutions • Unsaturated – Can dissolve more solute. • Saturated – Cannot dissolve more solute.

  8. Types of Solutions • Supersaturated – heating in order to dissolve more solute. • Normally for solids dissolved in liquids Click here for video clip. [http://wps.prenhall.com/wps/media/objects/476/488316/Instructor_Resources/Chapter_13/FG13_04.JPG]

  9. Heating works opposite for gases in solution. [http://cwx.prenhall.com/bookbind/pubbooks/mcmurry2/chapter11/medialib/FG11_006.JPG]

  10. Solubility • Measurement of solute that will dissolve in a solvent under specific conditions. [http://cwx.prenhall.com/bookbind/pubbooks/hillchem3/medialib/media_portfolio/text_images/CH12/FG12_10.JPG]

  11. Solubility • Solutions normally dissolve faster when: • Surface area is increased. • Solution is stirred. • Temperature is increased. (usually for solids!)

  12. Solubility • When dealing with gases, higher pressures causes higher solubility. [http://cwx.prenhall.com/bookbind/pubbooks/hillchem3/medialib/media_portfolio/text_images/CH12/FG12_13.JPG]
