  1. Mixture • One or more pure substances; • Blend….not a chemical reaction

  2. Soluble • Capable of being dissolved

  3. solution • One substance dissolves into another substance with out settling out. • Homogeneous mixture • Ex: salt and water

  4. solvent • Part that does the dissolving in a true solution • Usually the larger part of the solution • Water is the universal solvent

  5. solute • Part that isthe dissolved • Usually a solid such as salt • Usually the smaller amount of the solution • Can have more than one solute(ex: sugar and salt both soluteadded to water)

  6. suspension • Substance WILL SETTLE OUT unless constantly stirred • Ex: mud in water; sand in water

  7. colloids • Substances that DO NOT DISSOLVE and DO NOT SETTLE • Look homogeneous to the naked eye but are actually heterogeneous • Particles are actually large enough to scatter light known as the Tyndall effect; • Ex: mayonnaise, milk, jello • Do not need to shake or stir

  8. electrolyte • Substance dissolved in water that produces ions that can conduct electricity • Ionic compounds dissolved in water

  9. hydrophilic • Likes water • Do dissolve in water • Ionic and polar molecules in water

  10. hydrophobic • Fear water • Do not dissolve • Non polar molecules

  11. Ionic compounds with water • Break down into ions • Hydrophillic • miscible • Form electrolytes • Ex: salt and water

  12. Polar molecules with water • Hydrophilic • Do NOT form ions/electrolytes • Can have charged regions • miscible • Ex: sugar and water

  13. Non polar molecules with water • Hydrophobic • Ex: oil and water • immiscible

  14. adhesion • Attraction between dissimilar substances • Water spreads thin • Ex: water to glass

  15. cohesion • Attraction between similar substances • Water beads up • Water to water

  16. Surface tension • Cohesion of water at the surface

  17. Capillary action • Upward movement of water due to cohesion and adhesion • Ex: water moving up plant roots
