What is water chemistry?
Water chemistry deals with the chemical
properties and information about water.
One of the experiments that was preformed at Rio
Salado was testing the oxygen levels of bodies of water.
The bodies of water we tested was a small water fall and a rain water ditch.
1. Get a test sample
2. Add 8 drops of Manganous Sulfate
3. Add 8 drops of Alkaline
4. Cap the container and shake for 30 seconds
5. Allow contents to settle
6. Add 8 drops of sulfuric acid
7. Shake for another 30 seconds
8. Allow reagent and precipitate to dissolve
9. Transfer 30 ml of sample into a titration tube
10. Have partner hold the titration tube with the sodium thiosulfate upside down while you fill the titration syringe with it
11. Add the S.T until the sample becomes a pale yellow
12. Add 8 drops of starch indicator
13. Add S.T until the solution is colorless
14. Read sesults in mg/l Dissolved Oxygen
Rio Salado has more than just one place to it, there is the lower wetlands, storm drain area,and upper reservoir.
Dissolved oxygen is the oxygen content in
the water, this is needed for aquatic animals to live, and plants in the water as well.
The results were as followed, the colder water
held more oxygen than the warmer water because it allows for more water flow.
-Pollution is one of the worlds biggest killers. (Comparable to Malaria/HIV).
-It is caused by industrial fumes, vehicle emissions, sewage, chemical and oil spills, nuclear material, and household chemicals.
-Causes diseases such as cancer, lupus, immune diseases, allergies, and asthma.
-2,200 children die every day from pollution.

-14 billion pounds of garbage are thrown into the ocean every year.
-Over 1 million seabirds and 100,000 sea mammals are killed by pollution every year.
- We can stop pollution by doing simple in easy tasks like Using less electricity, Lower the thermometer in the winter, plant a tree, and turning the lights off as you leave a room.
Water is a essential to life on earth. People use up more fresh water than it is naturally replenished. Practicing a low water-use lifestyle is a way everyone can help
