Today in class, I started my experiment.
Procedure:
1. Put goggles, apron, and mask on
2. Put 12 8 cm piece of tape on a side of each of the 12 containers
3. Label each of the 12 cups differently with the sharpie pen: A1, A2, B1, B2, C1, C2, D1, D2, E1, E2, F1, F2
4. Rub sandpaper on each piece of metal thoroughly for 5 seconds.
5. Mark each piece of steel 1-6, and each piece of copper 1-6 with the sharpie pen
6. Weigh each piece of metal by using the gram scale, and record under its corresponding number (The letters refer to the different types of water pollutants, and the number 1 refers to copper, and 2 refers to steel)
7. Take a picture of each metal with the number facing the camera
8. Uncap the lid of each containers
9. Measure 35 mL Clorax in a measuring cup, and pour it into container A1
10. Repeat step 8 into container A2
11. Wash out the measuring cup with water, and dry it with a paper towel
12. Repeat steps 8-10 with Drano and B1 and B2
13. Repeat steps 8-10 with Ammonia and C1 and C2
14. Repeat steps 8-10 with Water and D1 and D2
15. With a measuring cup, measure 5 mL of sea salt, and with a graduated cylinder, measure 30 mL of water
16. Pour the water into the measuring cup with the salt, and stir it with a stirring stick for 15 seconds
17. Pour the salt solution into the container E1 and E2
18. Repeat steps 8-10 with Sulfuric Acid and F1 and F2
19. Put each metal part in its corresponding container (Copper 1 in container A1, Steel 1 in container A2)
20. Test each solution with pH paper, determine it's pH, and record in the data table
21. Shut each container with a lid
22. Every Monday, and Wednesday, take all of the copper pieces out, and run gently under water for 10 seconds
23. Gently dab at the copper until the copper is dry
24. Measure the weight of all of the copper pieces, determine the solution's pH, and record
25. Repeat steps 22-24 on Tuesday and Thursday with the steel
