Dissolving and Solubility

Dissolving

• Kinetic theory- Water molecules are always moving
• Ex. Kool aid-energy is transferred from Water to
  kool aid and sugar.
• All matter is small particles
• Particles are in motion (hotfast)
• Particles collide w/ each other (largerslow)

Key Terms

• Enzyme-protein catalysts
• Inhibitor-slows reactions
• Polar- and
• Nonpolar- same
• Saturated-cannot dissolve more
• Unsaturated- can still dissolve more
• Supersaturated-over limit, will precipitate out
• Solubility-how much solute can dissolve in a
  solvent

5

• Solutes w/ larger surface area dissolve faster
• Biggerslower Smaller piecesquick
• Stirring/shaking dissolve faster
• Increases diffusion, allows it all to spread out,
  instead of sink to the bottom
• Hot Temperatures dissolve solutes faster
• Heatincrease in energy
• More collisions
• Not every substance dissolves
• Soluble- able to dissovle- Polar/Polar or
  Nonpolar/Nonpolar
• insoluble-will not dissolve

Water A common solvent

• 2/3 Earths Surface is Water
• ¾ of your body is water
• Water is called the universal solvent
• The structure of H20 helps it dissolve charged
  particles
