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

6. 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]

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

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

12. Solubility Measurement of solute that will dissolve in a solvent under specific conditions. 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]

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

14. Solubility When dealing with gases, higher pressures causes higher 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]
