Unformatted text preview: 2. Draw a water molecule hydrogen bonded to 4 neighboring water molecules. 3. Explain how the four emergent properties of water relate to the structure and interaction of water molecules. 4. Compare/contrast: hydrophobic, hydrophilic and amphipathic substances. Be able to identify each type based on structure. 5. Calculate molecular mass, molar mass and molarity given atomic masses. 6. Calculate pH given [H+] or [OH-}. Calculate [H+] given pH or [OH-]. Calculate [OH-] given pH or [H+]. 7. Contrast acid & base and acidic, basic & neutral solutions (using pH, [H+] and [OH-]). 8. Explain how a simple buffer system will respond to an increase in pH and decrease in pH....
