Aquatic Chemistry

3. a basic substance has a high concentration of this
5. the name of the Adirondack Lake we will compare our pH and alkalinity water values with today
9. the ion product constant of water
10. carbon system (multiple carbon forms) that buffers pH in water
12. this legislation significantly helped improve air quality and reduce acid rainfall in the northeast USA
13. N2 -> NH4+ (nitrogen fixation) is an example of a ___________ redox reaction
14. a change in pH can alter the solubility of __________ in water
15. concentration of hydrogen ions in an aqueous solution
16. in lab, you must add an acid until the pH is below _______ to create your titration curve
18. the ability of water to neutralize or buffer acid
20. negatively charged ion made of one carbon and three oxygen atoms; important in buffering water

1. determining concentration by slowly adding a solution until a reaction endpoint is reached
2. lowest energy yield on a REDOX ladder producing “biogas”
3. loss of electrons; often oxygen-rich
4. involves the transfer of electrons, releases energy, and can lead to oxygen depletion in lakes and wetlands
6. “always add _______ to water, never the reverse” (lab safety rule)
7. a sudden drop in a lake’s pH, often occurring in spring snow melt season, when accumulated acidic compounds from snow are rapidly released
8. microscopic living organisms that drive nutrient cycling
11. the graduated cylindrical glassware that will be used to dispense the acid into water for the lab
17. the strong acid you will titrate with today
19. precipitation usually made by sulfur and nitrogen pollution in the atmosphere
